unfortunately I already bought everything from newegg is the gtx 660 way below the 760 in performance? I wanna be able to play games like assassin's creed, skyrim, and sims in good settings. (I know this questions is a bit unrelated but since you brought it up...)
is my power unit gonna be enough for it? this is what the item specifications say about the power supply: 500 watt or greater power supply with a minimum of 30 amps on the +12 volt rail. So technically my 500w unit will be enough. But will I have performance issues with it being the bare minimum?
