I have recently been looking at the two high end dominator ram kits. I was wondering, how much faster, if any, is the Corsair Dominator DDR3 1800MHz(7-7-7-20) over the Corsair Dominator DDR2 800MHz (3-4-3-9)? What is the bandwith difference and how much of a performance increase will you notice in games? Comparing 2GB to 2GB just to make it even.
