[Yatty]

Can i run a geforce gtx 260 if my computer has only 2 gigs of ram?

It should work just fine, but you might consider upgrading to 4 gigs later.

Your question does relate to the PSU only, here is PSU requirements for the GPU. http://www.realhardtechx.com/index_archivos/Page362.htm
And other info the windows system requirements, like win7 need 1GB RAM for 32bit, 2Gb for 64bit, etc. http://support.apple.com/en-us/HT204048
