Battlefield 2 Performance
We don't have SLI numbers for this game because it seems the way we run or benchmark has problems with SLI. From some FRAPS gameplay analysis it is clear that SLI does improve BF2 performance, but it just doesn't show up in our timedemo for some reason. We are still working on this problem. We were able to see a benefit from CrossFire, and we didn't think it'd be fair to leave it out just because we couldn't get a proper picture of SLI performance. While CrossFire does offer an advantage over single X1k cards, the X1800 XT can't make significant gains over the single 7800 GTX 512 without AA enabled.
With AA enabled, CrossFire offers a bit more of an advantage over any single NVIDIA card. It is unfortunate that our test is unable to capture the affect of SLI on performance.

Dunno what about 512gtx-Sli, but single one is http://www.pcpop.com/doc/0/121/121711_5.shtml">no more "the best of the best" since "eax 1800xt top" beat it in most d3d benchies. ( not to mention it's price some $20-50 more than standard xt)Fenixgoon - Tuesday, December 20, 2005 - link
D3D benches are different than real world performance - and for just about everything (if not everything, correct me if i'm wrong), the GTX 512 blows away the GTX 256 and x1800XT. The x1800 XTPE, or whatever's next in line, is *supposed* to compete with the GTX512. Almost seems like nvidia caught ati flat footed on this one.Vol2005 - Wednesday, December 21, 2005 - link
sorry, maybe i was a bit unclearbut the thing is that asus x1800xt-top IS x1800xtpe, indeed. And as you've just said the real competitor to gtx512 according to article that i refered.
As to real world perfomance, it's still uclear to me what do you mean.
Maybe i'm wrong, but aren't the majority of the modern games using d3d? Even if not so, i think these results are fairly enough prove that the gtx is no longer the fastest.
Of course, this has to be proven further by other reviewers

You should've bought it when it was released. It was available then. Nothing mystical here.Leper Messiah - Tuesday, December 20, 2005 - link
6 frame per second increase in 1920x1440? eh?Tanclearas - Tuesday, December 20, 2005 - link
Come on! There are over 100 people in EVGA's step-up queue waiting for the 7800GTX 512MB, but you have a problem with ATI's availability?!Nvidia got LUCKY with the 256MB 7800GTX that it was ready to launch with no real competition. Nvidia was able to sit on it until sufficient quantity were ready. ATI (sort of) launches the X1800XT and Nvidia falls back to the same old launch tricks. If you're going to hold one company accountable, you have to hold them all accountable!

LOL! That's some retarded logic you got there pal.Tanclearas - Tuesday, December 20, 2005 - link
So you're saying Nvidia's should not be held accountable for supply issues, but ATI should be held accountable? Please tell me you were being sarcastic.bob661 - Tuesday, December 20, 2005 - link
I'm saying it's retarded because when Nvidia released their cards, you could buy them that day. Unlike ATI that even SAYS it will be different this time around and STILL fails to deliver. If neither companies produce enough to meet demand then they underestimated demand and that's something different entirely.Tanclearas - Tuesday, December 20, 2005 - link
So ATI could have shipped about five cards to the top 10 retailers, and ATI would have completely fulfilled your expectations. They just would have "underestimated demand".That's a huge load of crap you're shovelling there. Both companies are still more interested in appearing to be in a leadership position than they are actually ensuring they are making deliverable products. I just can't understand why so many "journalists" have their heads shoved so far up Nvidia's ass they can count their fillings.
