I was wondering if the 550w power supply was a bit too much. I don't really want to change my power supply anytime soon, and plan on overclocking, but I know that too much wattage can sometimes means a decrease in performance. Will this be the case here? Thanks!
Edit: Yes, I read the "how much wattage do you need?" post, just wanted to clarify, in case.
