I know when I had my AMD system if I didn't install everything in a certain order I would get 2000 to 2500 less on 3DMark2001.Its really a strange thing and using an ATI Radeon 9700 Pro.With my Intel system right now 2.4B @ 3.42GHz and 9700 Pro I get arpund 16,450 running 1:1 ratio on memory.If I run 4:5 for DDR 474 something like that I get 16,948,but my memory is not stable at that speed.This with the video card "NOT OVERCLOCKED".With teh card oberclocked I would be around 18,000-18,500.
