What i need to know is that if i purchase a 330 Watt AC Adapter what kind of Graphics Cards can i run with it? I was looking at this 660 http:// because the 660 2Gb has a much higher PSU than my PC can handle (even With the Adapter). If this is not the Best I Can do, Please inform me of anything that will perform better.
If you are planning to upgrade your gpu, you should just buy a new power supply and replace the current one. That way you can get a bigger card, and that psu probably wont run much other than what was in the computer to begin with.
