Hello, I am planning on buying this graphics card, but I don't know what other hardware I would need to run it. I know for a fact that my current PSU cannot handle it. I also want to buy a new fan or two and 2 gigs of RAM. I need some help figured out what PSU I should get, what fan(s) I should get, and what RAM I should buy. Right now I have two sticks of 512 mb, and there are no extra spaces left.
