Whats up guys im a gamer. I play stuff like CS:S and wow. im trying to start playing other games nothing too serious like crysis (the graphics are good yes but a horrible game ><) im looking at a couple video cards in teh -$100 range. atm im using a 250watt power supply i think...its the stock one in a a6123w HP computer. could any of the following run on the power supply and which one is more bang for the buck regardless of the power supply. 9600 OSO, 9500 GT, HD 4670, or maybe even like an old school 8800 GT cuz i see they are below a hundred bucks now.
