I think it depends on the game tbh, in some the ram can be an issue. Others, not so. Personally i think lazy game devrlopers have a lot to answer for. Too easy now to fire out ports and forget about pc optimisation. In the 1080p market for pc gaming you have the 390 and the 970, the former has the vram, the latter falls short on that front. But both lack in the grunt department. 1080p is still a very common res, and factor in 120/144Hz, neither of theese cards are great for max settings. I play a few older games such as crysis 3, bf3/4. Even at 1440p a single factory oc'd 980ti will hit limits. Thankfully now im on a gsync monitor which helps a great deal.
