idk, it really depends on what you play. I can't think of any title in the last 4 years (except for maybe tomb raider for a very short period of time) that AMD outperformed NVIDIA and when NVIDIA (Or EVGA rather) releases their blackops classified airforce one edition 980Ti, that will be the single best video card ever produced in the history of the galaxy.
I can think of a lot of games that to this day still run like shit on AMD CPU/GPU - most of these are very related to the games bottlenecking at CPU / poor optimization, which is more of a reflection on AMD vs. Intel than AMD vs. NVIDIA, but it's still a relevant concern.
So if you play LoL, TF2, CSGO, other esports garbage, going for a sub 1000$ AMD build with a solid AMD GPU will easily run 4K res and most MMO's should too if you turn the settings down.
It's not going to run AAA releases at max settings and 4K and it's going to perform worse at a rapid pace going forward.

i7 related but outside of cache and internal software, I don't even think we're at a point where games are utilizing what these CPUs offer. When DX12 hits and people actually use it, maybe we'll get to that point, but most of the games I play run on one core, and most of what I play would really be great if they ran on 4 cores because they are all CPU driven games.
granted, if these games weren't shit they'd optimize their engines at the same time and I would actually see a performance increase from an AMD 6990 to an NVIDIA 980.
