the thing is i would like the NVIDIA GEFORCE 8800GTX 768MB PCI-E GRAPHICS CARD but it needs a 600w power supply which means i would have to buy a differnt case which would be expensive... i kinda dont wanna go all out and in a year i cant upgrade because of the **** power supply...any suggestions?

i cant wait for any games for ps3 i only have 2..havent used it in a long time
