So I currently have an had 7870 in my system and it still handles current game titles pretty well, but I would like to have some more performance and I have a ton of options to choose from and I can decide. I can get two hd 6990 for $200 maybe even less. I can get two gtx 960 for $200 (but I would have to wait a month till the guy gets his new cards and it's not garuntied that I get cards), I can get a second he 7870 for $75 to $90, I can get a gtx 690 for $120. I cant decide between these choices and was want some opinions on what to get.
