Don't listen to him. The only time Intel is that far ahead is at 800x600. When you get to ACTUAL GAMEPLAY RESOLUTIONS LIKE 1680x1050 and 1920x1080, you see VERY LITTLE DIFFERENCE because once you hit 60fps your eyes can't see anymore.
You moreso want to spend on the GPU. What resolution monitor will you use?
If it's higher than 1280x1024, either system will be MORE THAN FINE. The Intel may have 120fps vs. 100fps for the AMD, and if you go to TomZ own benchmarks you'll see what I mean.
If you get a 120hz monitor, you can see past 60fps. Twice as smooth to be exact (120/60 = 2). Just thought I'd add that.
