I am thinking of selling my MSI 580GTX Lightning Extreme GPU, but I have no idea what to list the price as. I can't find any on ebay or amazon. Newegg doesn't sell it anymore either. I am looking to upgrade to a 680 if possible. Should I hold on to my 580? Its a beast of a card with 3GB of vram and plays everything I throw at it, but these new 680's are really tempting. Any suggestions? Thanks in advance!
