Preka :
Then i will sell my gtx 660 and buy single 760 or 770 if my psu can handle it.
That sounds like a good idea. I was never really into SLI, I would rather have 1 really high performance card. Also you might as well change your power supply. It is pretty bad form the reviews I have seen. If you give me a price range and if you want it modular, semi-modular, or not modular, I can find you one.
