AMD Mainstream PC

To be completely honest, the AMD Phenom II X3 720 Black Edition is not quite the equal of Intel's Core i3-530. In our tests, it came in slightly behind in practically every single benchmark, regardless of how many threads the applications used. But it comes very close, and if you buy into the value-packed AM3 platform using the X3 720 as your entry point, you'll have plenty of other features to go along with it.

Besides, when you judge it on its own merits, the $125 2.8GHz Phenom II X3 720 Heka Black Edition is still a very promising processor. Like the Athlon II X3 435 Rana we recommended for our entry-level box, the 720 Heka is at the sweet spot between dual- and quad-cores in AMD's lineup, performing better than Athlon II X4s in benchmarks that favor fewer threads and better than Phenom II X2s in benchmarks that favor more. It's a powerful overclocker, capable of a stable 3.8GHz on air and up to 3.3GHz on stock voltage, and the Black Edition suffix means you'll have an unlocked multiplier to help you get there. And of course, as with any AMD tri-core, you have a chance of unlocking its hidden fourth core with ACC. If you don't see yourself doing a lot of multitasking or multithreaded work, you could easily shave $34 by going with the $91 Phenom II X2 550 BE instead; if you plan on doing 3D rendering and video editing all day, you'd can save $23 by purchasing the $102 Athlon II X4 630 Propus. But if you're not certain where your CPU might take you and you want to maximize the possibilities, the 720 Heka is the right chip at the right price.

And to house that chip, we've got not one but two bang-for-the-buck motherboard possibilities from Gigabyte. If you're not planning to buy a discrete GPU to power video and gaming, we recommend the GA-MA790GPT-UD3H, a full-sized ATX motherboard built around the 790GX / SB750 chipset. At the excellent price of only $90 after rebate ($105 without) the MA790GPT-UD3H features an onboard Radeon HD 3300 IGP with 128MB of DDR3 sideport memory, which beats both AMD's newer 785G and the Intel Core i3-530's Intel HD Graphics in terms of raw power. It also comes with Realtek's premium ALC889A 7.1 channel HD audio chipset and loads of opportunities for expansion.

The SB750 Southbridge provides the standard four flavors of RAID (0/1/5/10) across six SATA 3GB/s ports, four facing front; connectivity includes VGA, DVI and HDMI video-out, six USB 2.0, one 1394a, a combo PS/2, Realtek 8111C GbE, six audio ports and a separate S/PDIF optical out on the rear panel; and the board supports all current Athlon II and Phenom II processors along with 16GB of DDR3-1666 memory in four banks. The board's layout leaves something to be desired, with one of three fan headers and its three USB 2.0 headers sandwiched haphazardly amongst the PCIe slots, but it does include a pair of PCIe x16 slots (with 8 lanes for each in CrossFire), three PCIe x1 and a pair of PCI slots, in addition to an IDE header, two 1394a headers and a legacy floppy connector.

However, if you do plan to buy a discrete GPU, we'd recommend the Gigabyte GA-MA790XT-UD4P instead. For the same $90 after rebate, it loses the onboard video of the 790GX series but gains the newer Realtek 8111DL NIC for Gigabit Ethernet, one 1394b port and one coaxial S/PDIF port on the rear panel. It has a more sensible layout and a reputation for moderate overclocking that should serve you well if you decide to push that tri-core CPU to its full potential.

As with our Mainstream Intel PC, onboard graphics make even a $100 discrete video card optional, but it's somewhat more of a talking point when that 790GX graphics still doesn't allow bitstreaming of Dolby TrueHD and DTS-HD or 8-channel LPCM audio output over HDMI. Though the Radeon 4850 is our go-to budget gaming choice at $100, if you're looking for this AMD PC to pull double duty as a home theater box, you might want to consider a Radeon 5000 series card like the $100 Radeon HD 5670 instead.

    It is not cheap, since you have to pay at least $100 for the operational system, if you go Windows.

    However, OEM computers are designed to NOT be able to upgrade. The simplest example is trying to put powerful video a year later - the PSU will not be sufficient. Then, you will need to replace the PSU, but the case is proprietary and you will need new case too. If you pay attention to how many open slots for HDDs you have in Dell/HP, you will also realize serious restriction there. not to mention that Dell's internal design consists of strange and large plastic hoods for the fans, which are often obstructing new video cards. Also, you may just realize that the memory banks are only two on most OEMs, and hence you are going to double expenses if larger memory is needed.

    My suggestion: first buy nice and spacious case with 90 degree HDD cage and at least four HDD slots! Example - Cooler Master Elite 310 for $49 (cheap, but the cages are 90 degree on this one).Then get really good PSU - Corsair, PCP&P, Seasonic 750W and above - you need it for all the available connectors and capacity for indefinite future expansion. Then decide on the platform. I had Intel, just recently switched to AMD and I am very happy actually with what I got for the twice less money - Fry's deal on Athlon II X4 630 with free Asus 785G micro-ATX, total $130. Yesterday I replayed Crysis warhead, it runs smooth on Enthusiast 1920*1200, with Radeon 5850.

    Buy 2*2 GB DDR3 - there are modules on sale. I prefer Kingston Hyper X for stability. The idea is you want to start with at least two banks by 2GB so you have enough and still room for further expansion. The mobo should have 4 memory banks, not only two.

    I got micro ATX, next upgrade I can use the micro ATX for a home server box or HTPC. If you get full ATX now, you cannot use it for HTPC small factor later, because it's big. Of course, if building ultimate machine, the choice of components is different. mine is best bang for the buck for gaming and video editing. Spec:

    Asus A785M microATX, Athlon II X4 630, 8GB Kingston Hyper 1600 DDR3, 4*1TB Seagate Barracuda 7200.12 /not the 11th series- it's junk/, XFX Radeon 5850 regular, PCP&P 750W, Windows 7 64-bit Pro This comp gets 7.7 Win performance index. All components have frequent sale. Cut the memory to 4 GB, use HDD by your taste, use cheaper video and voila - you have power under $500. Intel configuration would cost me more. Instead I opt for the Radeon 5850. I transcode with Cyberlink Esspresso 5.5 or Avivo because are GPU accelerated. The last time it transcoded 4.31GB x.264 to PSP for 17 minutes :):). The Radeons are crazy stuff and under load temp is 42 Celsius. My previous G285 was going 81 Celsius under load and the entire motherboard was getting cooked.

    I agree about comparing to pre-built. The best bang for the buck in lower end builds is probably not building yourself anymore.

    For example, Gateway has a new Gateway DX4831-05 Desktop with:

    i5-650 @3.2GHz,
    8GB DDR3,
    1TB HDD,
    DVDRW,
    HDMI,
    eSATA,
    FireWire,
    Windows 7 Home Premium 64-bit
    G310 graphics card

    and this all comes in at $799 shipped free and no tax to most states. If you can find one refurbed you can cut another $100 off of that.


    So the prebuilt machine comes in at $150 less but is arguably a better machine with a better processor, more ram, bigger hard drive, and a warranty with room to upgrade to a better video card. Even if you tack on $100 for a better vid card, you still save $50 and get much better system specs overall.

    I know its not fun to just buy a PC anymore, but if you are not building a overclock hobby machine, it really pays to look around Dell, Gateway, HP etc for prices! (And hell, even gateway sells a $1299 i860 machine with a 5850, so even at the upper end, their are still good deals to be had)

    It would be nice to see a table with a price to PCMark (or other benchmark) ratio.

    More categories would be nice to. Instead of grouping by price range, group by category. So for instance:

    Grandma PC
    Cheap / Fancy
    Niether of which would have discreet graphics but maybe a small SSD on the high end.

    And also cover, workstation, gaming, HTCP, etc. It feels like in an attempt to give an overview of the whole market you're forgetting about actual uses.

    This first "entry level" rigg put together here isn't actually entry level. It's way too powerful and expensive for that.

    At entry level you'd choose Athlon x2 240 which is a very powerful and capable prosessor for those things you are supposed to do at entry level.

    2 GB memory is also more than sufficient. I'm not sure how much faster an entry level rigg gets in every day internet and office use if you put there extra 2 GBs? 0%? 2%?

    The power source is also both over kill and too expensive.

    What comes to MB, The 785G is ok pick up here but once again, the 780G offers almost identical performance. I know that 785G has other advances, so this choice is understandable.

    And understandable are all of these choices made here. I could easily do exactly the same line up for me and I would reason my choices exactly the same way. But as a result I'd end up having something else than an entry level PC.

    All in all, all I'm saying here is that this now called "Entry level" starting point should actually be called "best-bang-for-the-buck level".

    You put to this "entry level" rigg an ATI 5830 graphic card and you end up with a quite capable power house.
  • JarredWalton - Friday, February 12, 2010 - link

    The consensus at AnandTech is that we wouldn't touch 2GB machines these days; Windows 7 64-bit can run on 2GB, but we felt it was far more useful to bump it up to 4GB. How much faster it ends up being really depends on how you use your PC, but I know I frequently get a lot of HDD thrashing from swapfile access if I don't have 4GB.

    As for the power supply, you have essentially two choices: get a cheaper lower efficiency PSU for less money, or get something that's better but costs http://www.newegg.com/Product/Product.aspx?Item=N8...">at least $40. This is another item that has been debated in the past, and the result is that we're all a lot more comfortable spending more money on a higher quality PSU. That will also give you plenty of options for growing the PC down the road, along with overclocking.

    As someone else commented, if you're just looking for a standard system and you don't intend to upgrade, take a serious look at Dell/HP/etc. pre-built systems. They won't be faster than these builds, but at $500 for a complete setup you're not going to get equivalent components with a DIY. What you will get are more features and higher quality (with the ability to upgrade any and all components should the need arise). The OEM cases are still vendor lock in, unfortunately.

    To whit, I've got a friend's Dell XPS 400 at my house right now with an old Pentium D 820 (2.8GHz) and it's having problems. There's little point in trying to spend money fixing it when we can build a newer, faster system for less than $500. If I could swap out the mobo and CPU, we could have a "new" system in there for less than $200, but because of the proprietary chassis that's not an option.
  • FlyTexas - Friday, February 12, 2010 - link

    Regarding the Dell XPS 400 system.

    You are correct that it has a BTX motherboard, and thus can't really be upgraded in that case.

    However, even if you could, what are you saving? The motherboard + CPU + memory is what costs all the money in a computer anyway.

    A basic case will run you $50 including power supply (not a uber case, but one that works just fine), and while you can move the hard drive from the XPS 400, it is now out of date compared to a modern hard drive.

    That computer is now 4+ years old, the most valuable thing there is the Windows XP licence. :) (which you're not supposed to move to a new system, but Microsoft will do it over the phone anyway if you call to activate it on a new box)

    Regarding your friend's computer, since he doesn't need a new monitor, keyboard, mouse, hard drive, etc.

    All he really needs is the case, motherboard, CPU, RAM (maybe), and he is good to go. That doesn't cost $500.

    Just my random thoughts... :)
  • JarredWalton - Friday, February 12, 2010 - link

    Actually, I could keep the RAM (2x2GB DDR2), GPU (9800 GS), PSU, and case... and really, the XPS 400 series case is quite good, and the PSU is far better than the cheap stuff you get bundled with a case.

    The HDD seems to be having problems, but again I don't know if it's truly dying or just needs a reinstall. (I was able to boot into Linux to copy off the files, but trying to boot XP gives a BSOD no matter what I try.) So, at $50/hr to work on a computer, it's probably not worth saving.

    If it were my own PC, I'd put in the time and fix the HDD, but it's not so the question quickly becomes one of fixing old vs. buying new. Their feeling is, "why spend $250 fixing this old thing [i.e. new HDD plus my time] when we can get a brand new PC for a bit more that's going to be superior?"
  • FlyTexas - Friday, February 12, 2010 - link

    True enough about the RAM, assuming it isn't part of the problem. As a completely unrelated note, I've found memory to cause more problems in the past few years than anything else. 10 years ago I never had to RMA memory that I can recall, now I'm doing it maybe once a year. And I sold a LOT of computers 10 years ago.

    I have a XPS 410 myself, however no need to upgrade it because it came with a Core 2 Duo @ 2.4gHz. That machine is now my son's computer, but it used to be my main rig. Want to buy it as a "cheap repair"? ;)

    The second area that is unreliable are hard drives, however this seems less so now than 10 years ago. I generally won't use a consumer hard drive more than 4-5 years, they just weren't designed to be used much longer and I've had too many fail on me after that point. If that XPS 400 has the origional drive in it, you actually should get a speed boost by putting in a new one.

    Your comments regarding the cost to repair are spot on. I didn't know that you were charging for that work. In that case, REALLY don't bother, part it out and move on. At $50/hr, few 4 year old desktop computers are worth fixing.
  • FlyTexas - Friday, February 12, 2010 - link

    I disagree on the 2GB vs. 4GB comment, at least in my experience. Had the prices not jumped in the past year, I'd agree with 4GB, but right now it costs too much.

    At home, my gaming machine and my server both have 6GB, the rest of the machines have 2GB. They all run Windows 7 64-bit.

    My wife uses a Dell Vostro 410 with an Intel Quad-Core @ 2.4GHz. She actually does use Office (Word, Excel, & Publisher), Quickbooks, Adobe Acrobat (full, not reader), Skype, etc. She has a half dozen things running in the system tray (she has a Zune, a web cam, music player, etc.).

    2GB of RAM works just fine for all that. I actually have spare DDR2 sitting on the shelf, I've been meaning to put it in, but haven't made the time. Why? It doesn't need it and wouldn't really benefit the system.

    Now I know there are cases where you need more. The server had to live with 2GB for awhile when I had a memory stick fail. I noticed that difference. I don't think my main machine needs the 6GB however, 3GB would have been fine.

    Vista was terrible using memory efficiently, Windows 7 seems to be much better about it.

    All just my opinion of course... :)

    Hi there, JW!

    I couldn't agree more. I think all you said actually doesn't contradict what I said. I don't question the choices made, I just ponder over the phrase "entry level"

    Could I make a guess here for you? You wouldn't disagree with me if I said that this entry level rigg is actually pretty decent runner if you put in there a good graphic card? At least that's how I see things. Subsecuently, I can't help finding me smiling internally when we are talking here about entry level.

    I guess the reason for this awkward situation is that these days the components are both powerful and cheap. At least that is if you think back more than couple of years.

    As for the article as a whole, I think it was a pretty well shaped entré for SH.
