The 4770 is a fantastic budget card. It performs just shy of the 4850 I believe, for a much cheaper price tag. From what I've heard they OC like madmen, past the 4850 in some cases even. Get at least a 450w PSU from a reputable company. Go higher and you'll save money in the long run, but no lower than 450w.
