Hey guys i have a q6600 clocked at 3ghz and a 8800gt. Im planning to upgrade my video card. I want it to play call of duty black ops. The 8800 gt will run it fine but i want better. So which one should i get. I'll probably upgrade to an i7 in 2 yrs. So should i go for a gtx 460 and sli it when i do an i7 or go with a 470 for now. thanks.
