Benchmark Results: Crysis
We’re using Very High DirectX 10 settings here, yet, at 1680x1050, a pair of Radeon HD 5870s performs comparably to two or three GeForce GTX 480s. Clearly, there’s a platform bottleneck in play.
Similarly, 1900x1200 shows the same performance ceiling in place. The single Radeon HD 5870 and GeForce GTX 480 boards lose a bit of frame rate, but are still on par with each other.
Finally, at 2560x1600, there’s enough graphics load to differentiate every configuration. Going from one to two to three GeForce GTX 480s buys a sizable gain each step of the way, though scaling from one to two is most impressive. In comparison, the jump from one to two Radeon HD 5870s is nice if you’re not using AA. Turn it on and you’ll incur a huge performance hit—something we’ve seen several times in the last two years.

Why don't you overclock that cpu higher? Only 3.3 Ghz? The 3rd GTX 480 looks like it's being bottlenecked. You can see the scaling is excellent at high resolutions with AA (from 1 to 2 to 3 cards), but at lower resolutions without AA there's no gain.
and why not check it against the 5890, the 480GTX is nvidia fastest card, put it against ATI Fastest Card
There's a good chance that more CPU would def. help at the lower resolutions--one of the reasons I chose 2560 for the comparisons at the end ;-) For one reason or another, wasn't having much luck getting the retail i7-930/Eclipse Plus combo to overclock very well.

A pair of 5870s is actually going to be faster. Should I swing a second 5970, though, I do think a pair of 5970s vs. the three GTX 480s would be a good comparison!
Crappy ATi drivers.
Did I miss something, but there is NO mention of the power consumption of the 3 x 480's??
I have no clue where you people are getting this "5890" Statement from... They have the 5870, and then the next step up is the 5970... Is that what you're trying to say?

Bleh, it's late and it has been a long weekend. Edited
Quad fire with 5850 would have been nice (thinking back to a builder marathon with quad fire) to see if ati's quad cards made any improovement over last years ones. Also i agree with lunyone, I for one would have been interested to see the numbers on load for the 3 nvidia cards with the 800W gold power supply (and maybe a comment from you cris about what power supply u think is best for the job. Either go lower wattage but a high efficiency psu or higher wattage but lower efficiency)
Anyways, it was a informative article, looking forward to a full 512 sp card from nvidia and the second revision to the fermi core.

The only place where the "5890" exists is in ATI's folder under 'What to do if Fermi is good".
And yes where is the tri-sli power consumption numbers, there's no mention of it's omittance in the analysis.

Actually, addressed in a couple of different places ;-) As mentioned in the test setup section, the 3-way SLI numbers crested 900W under load. But because this was above the Enermax unit's max. continuous power rating, this almost certainly isn't a very efficient measurement. Not that it matters--the noise of three cards was so loud that it's simply not a realistic combination using the Eclipse Plus board.
Who wants to pay $10 for 1 fps?
I'm going to stick with my old 9600 SLI config that I spent $100 dollars on a few years back.

dummy...the 5970 is a dual gpu card, that's why it was not compared. as far as since gpu cards go nvidia is the fastest one out ther.
i wonder if nvidia strong armed toms into agreeing not to show tri-sli power consumption in exchange for the third card (of the available "tens of thousands" /endsarcasm)

He wasn't able to upload the results before the power outage caused by the setup.

Once again, it's like, mentioned in the story :-P
What couldn't get your hands on a 3rd HD5870? Also ATI makes Crossfire bridges long enough. I got 2 with my MSI K9A2 Platinum, and another one with my MSI HD5870.
I do wonder about how the results are presented. Its obviously given in a method that favors nVidia. The only results chosen to be highlighted are the only results that show AMD in a poor position. I think to present these findings to consumers is rather misleading and more information should be furnished so consumers can make a proper decision on a product.
Right now the most common resolution is 1680x1050. 1920x1200 is becoming more popular as well. At these resolutions even considering a single GTX480 as having a performance advantage is questionable compared to an HD5870. The HD5870 also scales better in those scenario. Yet the basis of your conclusion of consistent SLI scaling comes from the least favorable scenario for the HD5870 on resolutions that are uncommon. I don't think its a mystery why a lower memory card would perform worse doing a post processing effect at a large resolution. However, there is more to a graphics card then memory and its evident the difference in architecture choices at common resolutions.
always great articles from u chris, hoping u might take on the 5970 and 2x5970 soon.
So, I'm wondering how much of overclocking potential these GTX 480 cards have. Yep, they are running hot as it is. But, what if you throw liquid cooling on that 2X SLI setup to keep the temps at 35C highest. How far would they go then?
