Hey guys, just added another 5870 to my loop. I just didn't have enough money for the 7970 that I wanted. I'm really suprised at how well the crossfire set up is working BF3 works great on ultra minus AA. Just to test it out I did a Crysis Warhead bench on Frost and compared it to review sites that featured the 7970. I realize that this game is DX10 and that it won't use much for than 1GB of vram, but is this crossfire set up really more powerful? I also realize the 7970 was test at 1920x1200 and mine is 1920x1080, but I can't believe those extra pixels will result in a drop of 20 FPS.
Now that I look, I'm also beating out a 6990, am I dong something wrong? I do have a relatively high OC on both cards, 1030core freq and 1250mem.
Anadtech results: 50.3 FPS
5870 Crossfire: 71.41 FPS
Same graphical settings
Here is a result of the 7970 while OCed and on the same res of 1920x1080p. 5870 crossfire shows a 15% increase in performance.
Other Benches:
Newbie2009 was kind enough to get my some of his 7970 Crysis 2 benchmarks. Now the 5870 might seem more powerful in raw gpu power, but I needed a test that featured new technology to show the downside of have 2 cards from 2 generations in past. IE Heavy DX11 and teselation.
7970 OC Benchmark results: 91fps no AA, 88FPS x4AA
5870 OC Crossfire: 85FPS no AA, 38FPS x4 AA
Tesselation didn't seem to be the downfall of crossfire 5870's are for the most part, the FPS was competitive with the HD 7970. Adding AAx4 to the mix had the 5870's fall flat on their face as vram was maxed out, a huge difference in performance from the 5870's to the 7970. This makes me wonder hd 2gb variant of the 5870 would work on a benchmark like this.

I will say before hand the the results averageing to 71FPS are misleading as it was choppy as hells at some points, and smooth at others. That being said, with the way it ran, I'd never play with AA on on this setup(AA off was smooth as butter). I think this is a vram limitation.
