The specs look attractive on the GeForce FX 5900 Ultra, but the only difference is the size of the memory, and a little clock speed, but nothing you can't change yourself. At the current moment, no games are out that are going to utilize the extra memory. As for the clock, everyone can use a few more Mhz here and there and that can be changed easily thanks to the massive coolers nVIDIA cards use. The only use for large memory applications are 1600x1200 games with 4x AA and 8x AF enabled, which looks nice, but runs at 14-30 frames a second, which doesn't help gameplay at all. The extra memory is more of a marketing ploy than anything else, because no games or applications (except DX9 benchmarks) can take advantage of it. I own a 256MB R350 PRO and there is no difference from the 128MB version, except for a whooping 10Mhz increase in memory clock and that extra RAM. So to answer your question, don't buy it just yet. An ATI RADEON 9700 PRO is a defacto standard card for gaming, its cheaper, powerful, and has a full 8 pixel rendering architecture, where nVIDIA only uses 4 pixels in color and Z buffer operations and 8 in everything else. Save you money and get a RADEON 9700 PRO, I believe you will be glad you did, because with that money you save, you can buy something else for your computer.
