What is faster? 4GB SLI at 1066 or 8GB at 800 Ghz?

[muratgemici2003]

I can't SLI 8 GB's of Dominator memory at 1066 so should I just run 4GB's at 1066 SLI Ready or run all 8GB's at 800 Ghz?

8gb ftw, wat r ur uses, no matter what they are, id still go with eight, minimise cod mw2, nfs shift and crysis, and switch inbetween as i see fit, think of the power, once ddr3 catches on ddr2 will cost an arm and a leg, so buy now
