DDR vs SDR at high resolutions

[Diable]

In Anand's review of the Nforce he did all the gaming benchmarks using a GF3 at resolution of 640x480(here's a link)and the KT266A reference board was 21% faster then the KT133A reference board(in Quake3). My question is if you crank the resolution up to 1024x768 or 1280x1024 and use the same graphic card will the KT266A still be 21% faster then the KT133A or will the graphics card become the bottleneck and even them out? If the answer is they'll perform about the same why should any one buy a KT266A or Nforce based board when a KT133A board and a GF3 will equal there performance at high resolution?

Because some people don't buy a motherboard solely based on it's performance in Quake3 at 1024x768.

Almost certainly the graphics card will start bottlenecking the system, and the lead at 1024x768 would be reduced drastically.

Perhaps they will have a video card in the future that won't be a bottleneck at 1024x768, in which case the KT266A will be quite a bit faster.

Besides, many people arent buying a system just for gaming purposes and they may well be able to take good advantage of the higher performance.
And because one single game is bottlenecked by the video card at 1024x768 certainly does not mean all games will be. Many games are far more processor limited then video card limited as Q3 is.

Also, a KT266A would be a much better platform on which to base a future Thoroughbred processor then the KT133A.
