Looking forward to upgrade my pc within two weeks and i'm really confused in chosing ram kits. I want it fast and perfect for overclocking.
I've decided on q6600 G0 and Gigabyte EP45-DS4

i have several choices

G.skill PC2-8000 PQ

Mushkin Redline PC2-8000

G.skill PC2-6400 cl5 PI, is this the one which can be operated @ 1066 cl5 and 800 @cl4
