Hey guys, yesterday I posted a question about the GTX 460. I was told that the 5850 was a much better card for only a couple bucks more, but to use it I need to upgrade my PSU. So I'm wondering what power supply to get. The card requires a 500 W power supply and I need more to power everything else. So what supply should get? Should I stick with the GTX 460 or the 550 Ti and just forget the 5850? I'm a total PC noob so I'm sort of lost here
