I have a p31-ds3l mobo that only has one pci-ex16 slot(1.0) and a 430w PSU.I have 2 gigs of ram and a quad 6600 2.4 ghz CPU.First of all is it doable.And secondly is it worth it(I mean whether or not i can get everything out of the card without it bottlenecking and stuff).My goal here is to play the latest games on a decent framerate just by purchasing an affordable GPU.
