You already know my question, SO basically im planing a rig, I am going to have a i5-4670k (no overclocking yet) and will have one EVGA GTX FTW 770 4 GB, I would like to be able to have 2 of them in the future, I think I will use the EVGA SuperNOVA NEX750g 80 plus gold 750 watt psu do you need more details on rig? will this be enough power?
