Hey I joined the forum a couple of years ago but never actually posted! Anyway.. I'm upgrading my PC so i can play Bf3, I've just bought a motherboard : Asus M4A89TD PRO and i will be getting a phenom II x4 soon and may get either 4 or 8gb or ram. I will be keeping my 8800GT for the time being, so i can save some more money up, My question is.... Will a 600w (OCZ GameXtream) Psu power these components, I think it would be a struggle.. any one know if i should get 750 possibly 800?
