Hi all, I just ordered my second Sapphire 7950. I'm planning to rebuild most of my system next month including an i7 4770K and motherboard. I'm going for a high overclock on the CPU and 1100MHz on the GPUs. I'm thinking 850W should be enough to get the job done. I'm willing to spend for quality but I don't want to throw money away. I was thinking about this Seasonic: http://www.newegg.com/Product/Produc...82E16817151108 This computer is strictly for gaming so things like 80 Plus Gold are probably not going to be worth it since this computer won't be on too much. Thanks in advance.
