I got a 3gb gtx 780 in late 2013 for my new PC and i also have a 1440p monitor which i game on. Up until now the 780 has coped fine for up to 80 fps in most games going as low as 60fps in high demanding games like bf4 with mostly maxed settings, but now it seems to be struggling a lot specifically for far cry 4 which needs to have some settings on medium for me to get at least 50fps. So is it time to get an upgrade? The 980 is looking good and I may be looking at AMD's 300 series when it comes out. I could also buy another 780 for SLI but i would also have to buy a more powerful power supply than 600w, and the 3gb vram might limit the high resolution textures which is why i am leaning towards 4gb cards. The 3rd option is to wait for the newer generation of cards to come out next year. Another question is will my cpu bottleneck these more powerful cards (i5 4670k)
