I REALLY don't understand why people look at CPU benchies at 800x600 and say that one CPU beats another in games.... That's NOT the point of buying the best CPU to game with: to game at 800x600 so why bench it there?
Because it's nice to compare the CPU's and see which is stronger in a non-limited situation?
Look at it this way, if Conroe is crushing at 640X480, that tells you it'll give you much more strength down the road when you upgrade your GPU, maybe even two or three times, and the bottleneck switches to your CPU.
