I'm getting an AMD HD6850. I notice on their site that their recommended minimum PSU is 500W. I've got a 300W PSU. Is it really a problem? I've never even thought about PSUs before until I saw that spec, then opened my case and saw it's 300W. Not sure if I should upgrade it or not. Would appreciate your thoughts.
System is a quad core @ 2.66 with Windows 7 32 bit. Screen is a 24" @ 1920x1080. The HD6850 is I think factory overclocked.
