Morphing nForce4 Ultra into nForce4 SLI

Far Cry: x16 vs. x16/x2 vs. x8/x8 (nVidia SLI)
As we have seen in past SLI reviews that tested Far Cry, the performance improvements in this game were not quite as great as Doom3 and Half Life 2. Still, the performance improved from 5% in the worst case to 51% at 1600x1200 with AA and AF. There was also an unusual anomaly in the test results with x16/x2 dual video mode. In both Doom 3 and HL2, the x16/x2 mode was 3% to 12% slower. However, in Far Cry, x16/x2 is actually slightly (1.6% to 2.8%) faster than x8/x8 nVidia SLI.

What gets me is that SLI is still viewed by so many people as a "cheap upgrade path" for their graphics later on, and they use that to justify and SLI (or possibly a modded Ultra board).Has everyone who comments here forgotten that there is the option of selling your 6600GT when you fancy an upgrade, and buying a second-hand 6800GT to replace it? I think you'd find the upgrade cost from the 6600GT to 6800GT would be less than a new 6600GT would cost you, regardless of how much prices on new cards fall. The 6800GT will also outperform two 6600GTs in almost all games, especially at higher resolutions and quality settings.
Even if the second-hand price difference between the 6600GT you want to sell, and the 6800GT you'd want to buy isn't smaller than the cost of a new 6600GT; there's still the question of what are you going to do with two outdated 6600GTs when it's time to do a proper upgrade. Single 6600GT cards will be going dirt cheap because they'll be considered low-end, and nobody would buy two of them when much better single card solutions are available. A 6800GT will at least have some reasonable second-hand value still.
The only possible reason for seeing SLI as a viable upgrade option is if you're afraid of buying or selling stuff second-hand. In that case you're missing out on a lot of bargains.
SLI should only be considered by people buying 6800's, either both of them at once or the second within a few months. Considering the cost involved, they'd be fools to save a few dollars and hope the Ultra->SLI mobo hack works correctly for them.

#73 and it will all be moot because you won't have the bridge connector. You will either have to make your own or buy one from someone else. Either way, the cost will reach or exceed what you would've spent had you purchased the SLI board in the first place.AtaStrumf - Friday, January 21, 2005 - link
Some people still don't get the point of SLi. It's in the cheap, gradual upgrade path.This hack, if nVidia doesn't disable it -- driver support in case of SLi is extremely important - new games will require new drivers!!!, makes this an even better deal for the cheap bastards among us, because you only pay a slight premium for being able to cheaply uprage later on (66(8)00GT will be much cheaper when I buy a second one) instead of having to first cash out big time for an SLi mobo just to get into the SLi game.

#65, #66 - what is wrong with nVidia marketing different performance levels. Why do you feel you need to single them out for your wrath? Do you think the CD/DVD for Microsoft's OfficePro costs any more to burn than the one for their OfficeStanderd? Do you get mad at AMD preventing you from increasing the multiplier on their A64 chips?Sheez, it's a common buriness practice, everyone does it. If it let them lower their unit cost by producing both chipsets on the same line instead of needing different ones, then bully for them.

#63, I don't think you will be able to buy the 3D1 card without Gigabyte's SLI motherboard.I have two comments:
1) in your future benchmarks of SLI products could you add some games that may not have been optimized by nVidia? I don't think most people know about this: http://www.pcper.com/article.php?aid=99&type=e...
2) Maybe the nForce4 and nForce4-4X can be modded to add SATAII and the other features of the Ultra chipset?

#69 - My only suggestion is if you see the SLI board price as just too high for the initial introduction, the price drop over the next year will subsidise your next upgrade assuming it will be atleast a year until you go for a new video card. Of course what will be is just a guess.OriginalReaper - Thursday, January 20, 2005 - link
It's already $800-1000 on the 2x GPUs, I think spending a little extra for a the nV SLI x8/x8 is worth it over the Ultra SLI.Not that I'd want either solution at the moment.

Consider also, you can buy an SLI capable display adapter today with a non-SLI motherboard. In a year when you may want to upgrade your video by buying a twin you may also be considering a new, dual core CPU.Live - Thursday, January 20, 2005 - link
To all of you who does not see the point of this mod:The point as I see it is not to buy 2 * 400$ cards and then skimp on the motherboard. This is for the ones who can’t afford SLI today. Buy this motherboard and your SLI ready if and when cheaper cards are out or your preferences/financial situation changes.
I'm one of those people that hold on to my parts for at least 2 years. So it’s nice to know I have as many options in the future open to me with a board like this.
My bet is that SLI with dual core CPUs and games that are multithreaded and SLI ready from the get go like perhaps Unreal 3 or Far Cry 2 will make SLI look rather tempting.
Imagine playing Duke Nukem Forever which will come ...heh never mind ;)

#65 - Tell nVidia to "stuff it" and wait for the X800XL. Look people, we all did just fine before SLI and we can do fine without it. Corporations just love it when we are so convinced that we need something they sell that we call them names for taking advantage. Just don't buy into it.
