I recently bought a XFX Nvidia 9600 GSO ( Newegg link ). I tried installing it and its not even recognized. Its getting power and I can hear the fan but nothing. I then contacted dell and they said that I need a better PSU but that they could not tell me the extact problem. I then bought a 580W ( Newegg link )PSU to replace my current 300W PSU. I just want to make sure that after this, I will definately be able to run my graphics card.. Its rather fusterating.
