Tirando a falta do SM3 que faz diferença pra um placa dessas...eu n achei a diferença do "jeto" que vc tá mostrando ai uhahiUAUa :lol:
testes foram com o modelo X700XT

Final Words
As we have seen from our tests, the X700 XT packs a lot of punch into a small package. Most of the time its not quite enough to keep up with the NVIDIA 6600 GT, but the X700 XT proves its worth in the Source Engine Video Stress Test, and FarCry, and Unreal Tournament 2004. Most of the X700 XT's power shines through when anisotropic filtering and antialiasing are disabled (the exception being UT2K4). Current and previous generation OpenGL titles do show the Radeon X700 XT lagging the NVIDIA GeForce 6600 GT. NVIDIA has traditionally been stronger in OpenGL performance than ATI, so this is not really a surprise.
What is interesting is that we usually see ATI cards push past NVIDIA cards when aniso and antialiasing are enabled, but we are seeing the reverse this time around. This could be because NVIDIA has finally got a solution with the same number of pixel pipes at a higher core clock speed than a comparably priced ATI product. The NVIDIA part also seems to maintain performance a little better when its limits are pushed (i.e. at 1600x1200). This could indicate that NVIDIA is making more effective use of memory bandwidth, as the 6600 GT is actually running at a very slightly slower memory data rate.
It is possible that we are only seeing the X700 XT pull further ahead at lower resolutions and when AA and AF are disabled because geometry processing is a larger percentage of overall performance in those cases, but we don't have a very sound way of testing this at the moment. We have also not explored the impact of coupling these GPUs with a lower performing CPU. The added geometry processing power of the X700 XT may or may not help alleviate the strain on slower systems, though it doesn't seem likely that this would be a significant advantage.
In addition to it's other advantages, the NVIDIA GeForce 6600 GT is capable of being used in an SLI configuration. Whether or not this will prove to be worth the investment is still up in the air (we still don't have that bridge connector from NVIDIA), but certainly it poses a potential that ATI can't offer right now.
In the end, the GeForce 6600 GT is a more versatile solution than the Radeon X700 XT that can deliver higher performance at more demanding settings. The X700 is certainly not a bad card, and street prices still remain to be seen. At publication, we found a 6600 GT available for $209 on pricewatch, though street prices for the X700 are not yet available. Unless the X700 XT is priced comfortably below its $199 MSRP, or you need the 256MB of the X700 Pro, the 6600 GT is the way to go for midrange cards.
Eu não acho a X700XT ruim, mt menos a 6600GT, mais tem mts beneficios em comprar a 6600.
