I'm still deciding which parts i am going to buy for my next computer, and now im trying to decide between the 7900 gt or the 7900 gtx. My question has to do with the memory. my last card was a radeon x800 pro 256mb. In doom3 when i set the settings to ultra high, it reccomends 512mb video card though my computer with 256mb could still play it at ultra just fine. quake 4 on the other hand, with the same message, would not run on my x800 pro 256mb at ultra settings. does anybody know if a 7900 gt, with its 256 mb, could handle quak4 at ultra like my x800 handled doom3? or does quake at ultra high truely need a 512mb card?

I don't think that Doom 3 recommends a 512mb Video Card.... Doom 3 recommends having 512mb of RAM. A 7900GT should be fine for running Quake 4 or you can also go with a x1900 which is also a great choice, but if you must have the latest and one of the greatest you can go for the 7900GTX.

Im pretty sure the 7900GT can handle Quake 4 with ultra quality setting. My 7800GT 256Mb was able to do it having 425/1100 specs. My 7800GTX 256Mb can handle it, so the 7900GT with faster performance should have no problem with it. Besides rather buying the 7900GTX just get 2 7900GT for SLI then you get better quality and higher resolution with great performance. :D

For running Ultra High quality, yes, they do...

256mb cards have insufficient framebuffer size for the large textures involved in Ultra Quality settings, although the game is quite pretty even at high quality....

My apologies, I never saw that it required a 512mb video card for ultra high settings. I never played the game, just glanced over the specifications.

Couldn't two 256mb GeForce 7900 GTs handle the ultra high settings better than a single 512 mb GeForce 7900 GTX? I would personally get the two 7900 GTs, as they have the best price for performance ratio of high-end cards, and two GTs cost about the same (maybe like $50 more) than a single GTX. I also read that NVidia is introducing SLI physics, where the second card (or I guess last two for quad-SLI) has awesome physic-calculating capabilities and the first card does the graphical workload (as far as I understand), and it works with any SLI set-up. I think soon we're going to start seeing a far greater use for SLI than just increasing fps.
