Re: Question about an upgrade.
it will bottleneck. new cards are designed for the newest version of OS and by your spec, I don't think you can run win7 with 2 gigs of ram and still play games comfortably. Maybe if you have nothing but the game running. if you're looking into the 580, im guessing you are playing some intense games? if you arent, no need for 580. if you are, upgrade to a new pc.
