I haven't had a chance to check any new benchs especially with the newest driver available. I'm about getting ready to purchase the 2900XT 512DDR3 and I was just wondering where it stood performance wise. Even if it isnt for the games that I play I dont think I'll be disappointed but again just wanted to get an idea.
It just all depends on the application. Even though it may rise above or fall below the 8800gts 640, the value is great- just look at what a few driver revisions have done performance wise, almost beasting the gtx in some cases. I love mine despite the bulk and heat because it is simply a great card for the money and for the performance. They overclock well too (My HIS 2900xt is currently, when at full 3d speed, 833 core/ 875 mem and ilde/ load temps are a little over 55c and load doesnt climb over 65c). This is just my two cents. Peace.
well the 2900 beats the 8800 gtx in bioshock as well as medal of honour airborne.these are two of the best looking games i have ever seen.but then some games tend to cripple the card,like neverwinternights2.the 8800gts640mb performs more consistently than the 2900 and runs pretty much everything well,but not quite as well as the 2900 in most games
I asked the same question for my recent build and did quite a bit of research. The 8800GTX is generally the better card. Understand this: the only point in comparing the two is to predict which architecture will be more effective at running games in the future. Some people claim (and at this point it's pure speculation) that the architecture of the 2900XT will allow for better performance in next-gen games and with subsequent driver releases. However, in the near future, you can be certain that the 8800GTX will generally give you the best performance. In the distant future...I'd say that even if the 2900XT overtakes the 8800GTX the performance difference will be very tiny, so it's not worth taking the gamble in the first place.
Bottom Line: the 8800GTX offers better performance than the 2900XT, even the 1gb version.
