Cameron06, Have a look here - http://www.extreme.outervision.com/psucalculatorlite.jsp PSU Calculator :) I need a good, quietish card for my Media Centre, take the load off my E4300, (OC'd to 2.5Ghz) ATI's current offering doesn't stand out too well at the moment. Think I'll wait for Xmas when Vista SP1 comes out.
