Radeon X800 256 ($410)
"In terms of performances we see that, certainly in the case of DirectX, where ATI state most of their optimisations efforts have been going due to the number of titles that are released utilising the API, the X800 PRO is offering a healthy performance increases over ATI's previous high end board, the Radeon 9800 XT, to the tune of about 50% or greater in non system limited situations."
"I have been blown away by this card. The PowerColor X800 Pro performs extremely well in almost all benchmarks winning with a large margin where it counts. It may not represent a completely new architecture, but with speed and image quality like this I would be pushed hard to not recommend this card. The bundle is great, stability is good, ability to overclock is very good, image quality is close to perfect and (last but not least) the performance is good enough to max the detail in most games. What else could you want?
Keep in mind that you are going to need a very fast CPU if you want to utilize all the power of a video card like this. My reasonably fast CPU became a pretty big bottleneck in some benchmarks and games. If you’re stuck with a somewhat slow CPU then you might find you are not getting such a big performance increase over the 9800XT."
NVIDIA GeForce 6800 Ultra ($390+)
"What NVIDIA has achieved with the GeForce 6800 Ultra makes even experienced graphics cards editors shake their head in amazement and wonder. The performance this card offers will sweep graphics cards enthusiasts (the author included) off their feet and carry them off into a state of ecstasy in which they can only gape in awe at the sight of these simply amazing benchmark results - Freezinassin! Compared to the GeForce 6800 Ultra, the former high-end models Radeon 9800XT and FX 5950 Ultra often seem like nothing more than cheap mainstream cards... "
"1) Very high performance in current and future games.
2) The ability to play at 2048x1536 in just about any game currently available or soon to be made available, and
3) The ability to play virtually any game at 1600x1200 with 4X AA and 16X anisotropic filtering enabled at smooth frame rates."
Radeon X800 vs. GeForce 6800
"The most obvious point here is an outstanding performance. Radeon X800 crushes our old faithful Radeon 9800 XT, the best card from the previous generation. The performance is in general a slight bit just above GeForce 6800 Ultra, but to be honest, the margins were not bigger than that in the most tests it wouldn't matter. What was probably more impressive was how well X800 Pro went through the tests."
"The performance these two architectures have is somewhat similar. Things that differ are image quality, features and physical aspects. Because of better FSAA quality we consider ATi still to be on the lead. On the feature side the NV40 looks, on paper, like the most impressive with Shader Model 3.0. ATi have not been idle though, and the Pixel Shader 2.0b is at least a step forward although not as big as the one NV40 made. What ATi has got that nVidia has not is 3Dc, which could result in improved image quality and/or performance."
"As we see it, Radeon X800 XT nicks the golden crown from GeForce 6800 just by an inch. If GeForce 6800 Ultra Extreme in combination with new drivers can make it even or take the lead again remains to see. But disregarding our opinions this is an even fight that hardly has anything in common with the fight we saw between Radeon 9700 Pro and GeForce 5800 Ultra."
