Hey, I have a geforce gts 450 with an Amd Phenom II x6 1045t and 8GB RAM all on a Biostar A780L3G motherboard. I don't know how many watts my PSU pushes because I don't physically have the system yet and wasn't mentioned in the online listing. I found a card that seems like great value, the gtx 660.For around $200. Will iI be able to max out a lot of games? If not, can you suggest a better card for a similar price? Thanks guys!
