Splinter Cell: Chaos Theory Performance
Again, the X850 falls between the 7800 GTX and 7800 GTX SLI solutions. The 6800 Ultra SLI setup lags behind compared to CrossFire in this benchmark. The disadvantage here is that CrossFire users won't be able to turn on some of the more detailed shaders (which happen to use SM3.0).It's very clear that CrossFire competes well from a performance standpoint. But when it comes to feature set, NVIDIA still has ATI beat. The SM3.0 options do make a visual difference in SC:CT, and they're worth enabling if spare graphics power is sitting idle. We didn't run NVIDIA parts with SM3.0 because we like comparisons to be as "apples to apples" as possible.

There seems to be something wrong with the Splinter Cell scores.The 6800U gets the same 40.2 FPS for both 1600x1200 and 1600x1200 4XAA.
Yet the 6800U SLI gets 75.9 w/out AA and 53.7 w/AA.
I'm guessing that the 40.2 is incorrect for the single card with AA, and that the actual score is lower, probably around 30-35 (based on the X850 single card score).
Using the 30-35 FPS score as a baseline would mean that SLI has a 53%-79% improvement.
I'm not sure if these estimates are real or not, but I definitely think something is wrong with your numbers and that the ~34% improvemnt in your conclusion is incorrect as well.
Thanks,
D'oh!

all these crt users need to wake up and join everyone else. 99% of all gamers useing crts? phhf, only gamers that also have record players because they swear they can hear the differance between a record and a cd. that difference is noise. where as almost everything in you pc is digital, you guys choose to live with the noise/cross talk, other anamolies that plague your crts because of the d/a conversion, and the non-error correcting communiation.while i will enjoy my perfect geometery, no need to have all magnets placed miles apart, whinning at res to high. monitor flickering when res changes. and the fact is that 99% of gamers do not spend the big $$$. i mean hell like 70% of the video cards out there are on board. and i'm geussing only like 5% are high end that can go aboce 12x10 res. at 12x10 most people can play perfectly on there lcds.
grow up crt fanboys, and wake up to what is really happening, your crts are dieing, our lcds are getting better. who really wants a 100+ box with a 4 ft footprint on there desk. only gamer snoobs like you.

CrystalBay (and anyone else who cares) ... you want the bf2 demo we use? Email me and I'll send it to you.It is difficult to setup bf2 to get repeatable results, and I'd recommend that you spend some time inside EA's demo.cmd for benchmarking the game and reading various forums on the subject.
Just to let everyone know, we have to actually take the csv file bf2 generates with the frametimes for each frame and we average the last 1700 frames. DICE actually records frametimes for the loadscreen, and it's more acurate for us to use their recorded times than to use something like fraps.
That's all the "support" I'll give for the demo file, but if you still want it, feel free to ask.

I am impressed with the performance gain. Seems to be more than NVIDIA SLI.CrystalBay - Saturday, July 23, 2005 - link

My crt cost over a 1000 dollars. 23 inch mitsubishi.there's nothing on the market that beats a crt for gaming. you have to be smoking some seriously badly cut ghetto crack to consider that an lcd is anything besides prettier,thinner and easier on the eyes than a high quality crt. And really, it is only easier on the eyes for doing 2d work, well, except for when the pixels get in the way of the font being perfectly round and clean, then it sux there too.
even a skank level crt beats out 600 dollar lcd's.

I have been a skeptic of SLI/Xfire and the like. I guess I just don't see the need for two cards, although I'm sure there is one or two reasons. I bought the 850pe earlier this year and I have to say I still don't regret it, even if it was overpriced. I'm thinking I will just keep using this card until R520 reaches the surface. Then I will be able to decide whether to buy the x850 master, or just do what I've always done and get the next single card in either the mid or high end.
