Also, now that I'm home and rested, I should mention a few things as follow-ups to my GeForce 6800 Ultra review. I was in quite a rush to get the review together, and I couldn't spend the time I wanted investigating these things beforehand. First, I was smoking crack when I said the GeForce 6800 Ultra would likely break 13K in 3DMark03 with a faster CPU. Clearly, GPU overclocking would have to be involved in any such feat. Second, I believe the 8X antialiasing mode on the 6800 Ultra is 2X multisampling and 4X supersampling, which would explain the big performance hit, the texture image quality differences, and the four different texture sample points. I am waiting on confirmation of this point from NVIDIA, but I believe that's the case.
Oh, and if you've bought memory recently, perhaps you can answer my question.
