ok, my question has to do with RAM speed. my friend has ddr2 1200 and is running vista. when he goes to the vista experience index thing, it gives him a rating of 5.6. now, i have ddr2 800 and i get 5.6 rating for ram too. Is this wrong or am i not understanding something, i would imagine he would get a higher score because his ram is faster, right? is it actually worth it/can you see a performance difference between, say 800 and 1066 RAM?
