We know how to read. You don't know how to read. If you would've read my entire context you would've realized my point.
Upgrading to anything below 970 is NOT worth the money. If you don't have the money for a GTX 970 there is
NO reason for you to upgrade the graphics card. 750Ti or 960 can give you a
short time solution, but in your case the performance upgrade is somewhere in lines of
10% which is not even close worth spending money on it.
One option that wasn't discussed earlier is getting another 7850 for CrossFireX. If you have atleast 750W PSU and a motherboard with enough PCIe lanes. 2x 7850 has enough power to run big titles in 1080p. But then again 7850 aren't really sold anymore even if you had the PSU and motherboard. (7850 crossfire is almost as powerful as single 970)
Don't get me and @
CJacko wrong. We are just trying to not make you waste money on silly GPU upgrade what doesn't benefit you.
