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.

Sigh.. Read comment to first post..DerekWilson - Thursday, July 28, 2005 - link
We're all still getting used to the new design :-)To actually reply -- the crossfire card can work alone. you don't need another card. I know this because it was running by itself while I was trying various methods to coax it into submission :-) ... Also, even if gigabyte's hardware is close to complete, ATI is in charge of the driver for the mobo and the graphics card, as well as getting a solid video bios out to their customers. These things are among the last in the pipe to be fully optimized.
I don't think I could give up the F520 even for desk space. I'd rather type on an LCD panel any day, but if I am gonna play or test games, there's just no substitute for a huge CRT.

Want to know why 1280x1024 always looks wrong on CRTs? It's because IT IS wrong! 800x600, 1024x768, 1600x1200 -- all are 4:3 aspect ratio,but
1280x1024? That's 5:4! To get 4:3, you need to use 1280x960! That should be benchmarked too, if possible.
Whoever invented that resolution should be forced to watch a CRT flickering at 30 Hz interlaced for the rest of his life! Or at least create more standard resolutions with the SAME aspect ratio!
I could rant on this endlessly....

There are a great many lcd panels that use 1280x1024 -- both for desktop systems and on notebooks.the resolution people play games on should match the aspect ratio of the display device. At the same time, there is no point in testing 1280x960 and 1280x1024 because their performance would be very similar. We test 1280x1024 because it is the larger of the two resolutions (and by our calculations, the more popular).

True!I'ld have to agree with Derek. Most people that play on 1280 use 1280x1024. But it is also true that 960 is the true 4:3... While I don't know why it's so that there's 2 versions of 1280 (probably something related to video or TV), I also know that the performance difference is allmost zero, try for yourself. Running Counterstrike showed no difference on my computer.

Nothing wrong with 16x12 adn sli'd 7800's. If your monitor can't go beyond that, then surely it would welcome the 8 and 16xaa modes that come for free, besidesvision33r - Saturday, July 23, 2005 - link
For the price of $1000+ to do Crossfire, you could've just bought the 7800GTX and you're done.coldpower27 - Saturday, July 23, 2005 - link
Well Multi GPU technology to me makes sense simply when you can't get the same performance you need out of a single card. I would rather have the 7800 GTX then the Dual 6800 Ultra setup, for reduced power consumption.You gotta hand it to Nidia able to market their SLI setup to the 6600 GT, and soon to be 6600 LE line.

I have to say im running a SLI setup.i went from a AGP based ( nf3, 754 a64 3200+ hammer ) 6800GT system, to the current SLI setup ( nf4 SLI/s939 3200+ winchester ) dual 6600GT setup.
to be honest, SLI aint all that. i miss the fact that to use my dual desktop ( i have 2*20inch CRT's ) I have to turn SLI off in the drivers, which involves a reboot, so thats hassel. Yes, the dual GT's beat even a 6800 ULTRA in non AA settings in doom 3 but they get creamed with AA on, even the 6600GT'S i have are feeling cpu strangulation, so you need a decent cpu to feed it. and not all games are SLI ready. To be honest, apart from the nice view in the case of to cards in there ( looks trick ) i would rather have a decent single card set up then a SLI setup.
crossfire is looking strong though! AIT needed it and now they have it, the playing field is much more level! karlos!

Also, as far as XFire competing with SLI, it seems to offer nothing really different from SLI, and in that sense only competes by being essentially the same thing but for ATI cards. However, NV is clearly concerned about it (as evidenced by their AA improvements, the reduction on the SLI chipset prices, and the improvements in default game support). So, ATI's entry into the dual card arena has really improved the features for all users, which is why this heated competition between the companies is so good for consumers. Hopefully ATI will get their XFire issues resolved quickly, although I agree with the sentiment that the R520 is far more important than XFire (at least in the graphics arena - in the chipset arena ATI probably can't compete without XFire).-D'oh!
