I want to upgrade my graphics card. right now I have a gforce gtx 770 and I have around $200 to $350ish dollars to spend. I have an AMD Radeon rx480 8 gigs on back order for $240 and I was thinking cancelling the back order and either buying a different card or buying a 480 on amazon in stock for $340. Should I keep waiting for the 480 to get back in stock on new egg? should I buy a different card and if so what card?
