In November of 2013, I built my PC, and I have no complaints with it to this day. I was wondering, however, when would you suggest I upgrade my GPU? I have a GTX 760, and I think it performs very well for what I paid for it, but with new games like GTA V and Killing Floor 2 coming out that may be slightly more demanding than games I am playing right now (CS:GO, Payday 2, NBA 2K15), I am worried I won't be able to run these new games at a quality I am used to. When do you think it would be worth it to upgrade my GPU? (Bottlenecking is not an issue as my CPU is a 4th gen i7 and I have 8GB of RAM) I would like to spend no more than $400 on a brand new GPU when I do upgrade, so price-to-performance ratio is very important to me, and SLI is out of the question. Please let me know what you guys think.
