Hi,Sorry to bother but a friend of mine recently got a sli gtx 660 ti. He has a 650w Thermaltake. Core i7 950. He gets random Lags with the SLI enabled. But then its fine with it disabled. No lag and same setting, there is a drop in fps though. Im thinking it is his PSU. What do you guys think. I dont want him buying something he doesnt need.
