I currently have a 3570k @ 4.2 and a MSI Twin Frozr 7850 gpu that I have had for a year now. Looking to upgrade the GPU at some point. I really don't plan to spend anything more then like $250 because I really don't game enough to spend gtx 770 money. So would upgrading from a 7850 to like a 7870 XT be pointless?? Also, I am interested in the GTX 760 or 7950. But since the 7xxx series are getting old and at some point the 8xxx should be released is it worth while?
