Hi all, I am building a new computer and have already got the Case, Motherboard, Hard Drive, DVD writer, CPU cooler, Neons and i am waiting on the RAM. Next i plan to buy the Power Supply. But i am stuck on which one to buy. The Corsair HX650 or the HX750. I plan to overclock this new system as high as i possibly can. The final specs will be: AMD Phenom II x4 955 CPU Gigabyte GA-890GPA-UD3H Motherboard 4GB Kingston HyperX DDR3 1600 RAM 1TB Samsung SpinPoint F3 HDD 2x HIS Radeon HD 6870 video cards NZXT M59 Case 2 sets of cold cathodes are going into this system. 2 red ones and 2 blue ones. So will the HX650 power this system fine. Or will i be better off getting the HX750, which is only $60NZ more then the 650. Cheers, Nathan.
