Final Words
To briefly recap our performance tests, we found that the new 8800 GTX provided the highest level of performance out of all of these cards. This was followed by the BFG and EVGA GeForce 7950 GX2s, along with the 8800 GTS and Sapphire's Radeon X1950 XTX. The GX2 cards placed slightly higher in Battlefield 2 while the 8800 GTS and X1950 XTX scored higher in The Elder Scrolls IV: Oblivion, with the GTS taking the overall second place crown. The next best performers were the Sparkle Calibre 7950 GT and the rest of the 7950 GTs. The Leadtek WinFast PX7900 GS TDH Extreme led in performance for the 7900 GS cards, then the EVGA 7900 GS KO, and lastly the Albatron 7900 GS. The next best performer was the MSI NX7600 GT which led in performance against the HDMI 7600 GT cards. The Gigabyte 7600 GS was the lowest performing NVIDIA card, and the ATI Powercolor X1600 PRO was the lowest performer of them all.
Looking at CPU utilization during Blu-ray playback, we saw that ATI cards generally did a little better than NVIDIA ones, and the 8800 GTX and GTS did particularly well compared to other NVIDIA cards. It is important to note that the only tests we could run today are with MPEG-2 decode tests. Unfortunately, this says nothing about the relative performance of heavy duty encoding formats like H.264 and even VC-1 (which will be used more frequently for future BD and HD-DVD content). The only thing we can say at this point is that lower CPU utilization is better. Just how much better in the long run won't be clear until we can test higher bitrate content in other formats.
Power consumption may be more of a factor in choosing a graphics card for video and gaming, especially if the main purpose of the card will be in a home theater system. Higher wattage power supplies sometimes require bigger and noisier fans to stay cool, and this means more unwanted system noise. We tested power consumption for both 3D acceleration and BD playback and looking at both of these some cards naturally did better than others. One of the cards that was noteworthy for consuming a lower amount of power is the Albatron 7900 GS. This card got the lowest power draw of the 7900 GS cards during the 3D acceleration tests, and did well in the BD playback power tests as well. The Leadtek WinFast PX7900 GS TDH Extreme was less power-hungry in the BD playback power tests, and drew average power loads in the 3D acceleration tests. A few cards you might want to stay away from if power draw is a concern are the 7950 GX2s and the X1950 XTX (as well as the 8800 GTX and GTS, of course). These cards are the top performers, but their high power draw (and cost) is an unfortunate downside.
GPU heat levels is something we looked at and the only card with any real issues here were the two silent GPUs: the Gigabyte 7600 GT HDMI and the XFX 7950 GT. Both of these cards saw much higher heat levels than the rest. Looking at noise levels though, these two cards happened to win the award for least amount of noise, a no-brainer seeing as how both cards have no moving parts. A few other noteworthy cards were the Leadtek WinFast PX7900 GS TDH Extreme and both of the 7950 GX2s from BFG and EVGA. It's especially nice that a card with the power of the 7950 GX2 runs so quietly. On the noisy side, the EVGA 7950 GT KO and ASUS EN7600 GT HDMI both had pretty noisy fans once they kicked in during stress testing. The Sapphire X1950 XTX was fairly noisy during operation as well.
Because HDCP and accompanying technologies are so new, we encountered problems or quirks with a few of these cards. Some of the cards, like the HDMI Gigabyte 7600 GS and ASUS EN7600 GT, were only able to play our Blu-ray movies over HDMI and not through the DVI port. Conversely, we found that with our MSI NX7600 GT Diamond Plus, the Blu-ray content wouldn't play through the HDMI connection but it would through the DVI port. These issues can generally be solved by converters, but it's still a bit of a nuisance. Unfortunately, an HDCP key ROM is required for each display output in order to allow protected content to play over both. Oversights like this should be remedied in the future (at the expense of either the manufacturer or the end user). For now, consumers should be aware of the situation.
We've looked at our test results and we know who the top performers are, but in order to attribute the overall value of these cards, we have to take a look at their prices. One card we feel stood out from the rest in this roundup was the XFX GeForce 7950 GT. This card offers high performance and completely silent operation, which makes it ideal for those who want an HDCP solution for a home theater system and a powerful card for gaming in the same package. At about $300 however, it's a bit on the pricey side, but it's not much greater than other non-silent versions of the same card, which adds to its value.
We also found the non-HDMI version of the MSI NX7600 GT to be of good value, considering its price and performance. It can currently be found for around $160, but some places are offering a mail-in rebate that would bring the price down to around $141; a great deal for a card like this if it can be found. The card's fairly quiet operation and its factory overclock (and cool operation which might provide good results for user overclocking) make the MSI GeForce NX7600 GT a good deal at this price.
If you absolutely must have the highest in gaming performance while still having HDCP capability, obviously the 8800 GTX is your GPU of choice, followed by the 8800 GTS. Beneath that, we would recommend going with the Radeon X1950 XTX over the GeForce 7950 GX2. The X1950 XTX is somewhat noisy and more power-hungry than the 7950 GX2, but the X1950 XTX is currently $100+ cheaper than the 7950 GX2. Considering the 3D performance difference and other benefits (low noise, etc.), the GX2 may be worth the extra money depending on user preference. For this review, however, the X1950 XTX clearly does more to assist the CPU in decoding current BD content.
For those users looking to spend the least amount of money on an HDCP compatible card, we would point again to the MSI NX7600 GT over the rest. The X1600 Pro from Powercolor might be cheaper and has a little lower CPU overhead, but its 3D performance is so low that we don't recommend this card if you plan to do any gaming at all. Besides, for about $35 or $40 more you can have a 7600 GT with a factory overclock, which will perform fairly well with a lot of games and can hold its own in BD playback as well.
In closing, because these cards are officially HDCP compatible, they are all candidates for the graphics solution in a system with high definition optical drives. The fact that both the graphics card and display device must be HDCP capable, and most displays and graphics cards that people are currently using aren't HDCP compatible is a problem for consumers in general. Most HDTVs produced in the past several years should support HDCP, however, so if you've upgraded recently, this might not be an issue. Unfortunately, almost all LCD and all CRT computer monitors are going to need an upgrade if HDCP content is in your future.
As we said before, these compatibility issues will defintely serve to frustrate and confuse PC users looking to upgrade their system in order to watch high definition movies. We aren't sure how those on the technology side may ultimately help alleviate some of this burden on consumers. The greatest irony is that where legitimate HDCP protected content won't work on some consumer's hardware, pirated videos should work without problems. We can only wonder if the money being poured out in a massive effort to crack down on movie piracy will ultimately be worth the hindrance this has caused the average PC user, or if it will simply drive more users to look for illegal video sources. Talk about biting the hand that feeds you...

We chose Click because of it's bitrate, not because or its artistic value :-)msva124 - Thursday, November 16, 2006 - link
Not really. The industry conforms to the the buyer, not the other way around.Josh Venning - Thursday, November 16, 2006 - link
Thanks for the comment, but the fact is that in the war against piracy, there is a lot of collateral damage.. Movie industries don't care if the consumer dislikes the fact that they have to upgrade their system in order to play the movie with the newest copy-protection standards. They only want to get rid of the pirates at whatever cost. This is why ultimately, everyone will have to conform.. or else not enjoy the benefits Bluray and HD DVD have to offer.LoneWolf15 - Friday, November 17, 2006 - link
However, if people fail to adopt (or are extremely slow to adopt) HDCP and balk in enough quantity, the resulting drop in sales would likely force the content industry to rethink its position.Don't think that I believe this is going to happen; I believe most consumers are sheep, and they'll go out and buy what is needed. Some of them may even pitch a fit that they have to, but they'll still likely do it because they want the content more. If Jane and Joe consumers across the globe said "We won't buy it" though, I think things would change. They would have to, or the loss in sales would eventually drive the content industry out of business.
Gives me a chance to remind myself that sometimes Sunshine/Outdoors 1.0 beats a home theater though, when the choice is available. :)

But the industry is feeding the consumer the line that this is the only way it can be. The average consumer doesn't know or understand that things /could/ be done a different way.The average consumer doesn't realize what he or she is giving up by buying into the industry's FUD. Pirates don't rape artists of their money. The very studios the artists work get their first.
It'd be great if everyone would boycott BD and HDDVD. But it's not going to happen.

I agree, Derek.One thought...considering that this was an HDCP review, I'd enjoy seeing a followup that did some work with evaluating video playback quality. I game, but I want an all-round card solution. This explains why I got rid of my Geforce 6800 --good gaming card, video playback was average quality on supported accelerated formats, and nVidia's PureVideo (rev. 1, or should I say 0.99) fiasco drove me away from them.
I'd be very interested to see how the current PureVideoHD and Avivo technologies square off, both in CPU usage under H.264, but also playback quality.
And, while I know things could be done a different way, my pessimism towards the future is high. It explains why HDCP support was a requirement in purchasing an LCD panel this week. This really stinks, I'd have chosen standard-aspect over widescreen except for that (almost no 20" standard displays with HDCP; I say almost rather than none, but I didn't find any). I had to get a much bigger widescreen to make up for lack or vertical height relative to a standard-aspect display.

Not always - see the record industry for the ideal example of those that do not conform to anything other than their own outdated models.I'm an enthusiastic capitalist, but some industries or industry groups have been unable or unwilling to adapt to the rapid pace of technology driven change in the internet era. Such groups have oftentimes fallen back upon legal attempts to force the marketplace into accepting their idea of how buisness should be done. The RIAA and the companies it represents refused to understand the oppurtunities the internet created for them, AND they refused to offer the product the consumers desired, because it didn't fit their model. The iTunes success story has forced them to sit up and take notice, and now rather than try to finally offer what customers want, they continue to wish to put the genie back in the bottle, and try to offer digital content to consumers only when it can be made 'safe' through DRM. DRM is NOT a market driven movement, it's a movement that attempts to remove one of the central features of the internet era - increased ability to steal content. Well fine, but the studios must think they exist in a vacuum because all they want to talk about is that negitive, not the positive factor of FAR lower distribution cost, and zero physical production cost. So we have all this focus on piracy protection, at huge cost to the end-user, that has essentially reduced the product purchased from a copy of the original work, down to a semi-permanant pay-per-view license, but the cost of the 'product' has remained the same.
Tell me where the market forces are here?
DerekWilson - Friday, November 17, 2006 - link
The market forces are neatly tied up and tossed out with the garbage thanks to the VERY anti-consumer DMCA (digital millennium copyright act).We can hardly even ask for what we want without being shot down by the DMCA.
Sure, we still have "fair use" rights. But the problem is that we can't touch the content to which we supposedly have fair use due to the legal protection afforded encrypted content by the DMCA.
If we were given unprotected movies, it would still be illegal to copy and distribute this content. It's almost like car manufacturers making cars that could only be driven by one person: it's still illegal to steal a car, but now the owner is restricted in his legal uses for the car. The comparison is even more accurate if there were laws in place to keep the owner of a car from circumventing the restriction to allow another person to drive it.
The only thing that DRM does is keep us from the myriad legal uses we could have for our movies (and music for that matter) that don't fall under just watching and listenting. Or didn't you know you had any right to use that content in other ways?
We couldn't even show you screen shots of the movie to compare image quality -- screen capture must be disabled during video playback.
Sorry for the rant -- this stuff just really bugs me.

Well, me not.Before , at college I didn't buy a single DVD cause I have no money to spend on unnecessary stuff.
Now I buys some DVD here and there.
But hell!
To ask equivalent of $30 for a DVD in a country where average daily wage is $25!!!
Also, to send some ***hole from RIAA analogue to saturday local middle school kids performance to have them pay $200 for singing some 30yrs old forgotten song on public area!!!
Are they crazy? [Yes, they are.]
I rememmber the co-called "totalitarian" communism jet.
And I can say, in that era people had far more liberties than they have in US now.
Sure, one can have a gun now. But he can't even sing or use some frickin publicly known math algorithm someone pattented. WTF?
Lets' patent the wheel!
20yrs ago we could not critisize the government here. But pretty much anything other than that was allowed(legal). From owning (registered)guns to singing whatever your mouth was capable off.
Now we are gonna have all of the wondelfull liberties ... or, better said, the corporations are gonna have all the wondelfull liberties.
To topic: what happens if you use analog output? You mentioned that the playback software asked for analog output when non-HDCP card was found...
AGAC - Thursday, November 16, 2006 - link
I thought I was going to read an article to help me choose what hardware should I have if I wanted to playback some HDCP media.Gaming benchmarks? Great! So now I know that a Geforce 8800 GTX is faster then a Radeon X1600! Thanks a lot.
What about OS settings, WinXp and Linux compatibility (is BluRay for Vista only?), monitor options, which card supports video in, why monitor manufacturers don´t advertise their HDCP compliant displays? Should I buy a desktop monitor? Should I buy an HDTV? what about all of it? So many questions...
I read it all and still don´t have a clue.
Sorry for the rant, guys. It´s this HDCP joke they´re playing on us all. Blockbuster video nearby has HD-DVD and BR titles and I laugh at the shelf because I want to play those in my pc and don´t know how to do it. I don´t remember having so much trouble with computer media since the days with my MSX computer and it´s cassete tapes back in early 80´s.
Regards from Brazil.
