No. Ive seen benchmarks in BF3 showing slight FPS increases with a hyperthreaded part, but that is a outlier and not the norm.

I only think it would be a bottleneck at 4K or on some really CPU intensive games. Digital foundry found that even the 5820K was a bottleneck in some cases. CPU's can't seem to keep up with 4K 60FS.

The only benefit of an i7 is Hyperthreading, so unless you have applications that can recognize that you won't see a difference. CPU Core Clock matters more than HT in most cases. A 4690K @ 4.8 GHz is going to edge out a 4790K @ 4.4 GHz in applications that don't take advantage of HT. In HT heavy applications and games however (ie Crysis 3, BF4 ... etc) the i7 is going to be 20% faster clock for clock than an i5 of the same generation.

Pretty sure you've got that backwards. The higher the resolution, the LESS the CPU matters. At 4K, it's entirely reliant on the GPU at that point. I'm not saying that AMD and Intel are evenly matched at that high end resolution, but 4K won't cause your CPU to suddenly become the weakest link in the mix of everything else. The lower the resolution, the more impact your CPU has on the game.

then yes, it will be a bottleneck if you're shooting for fairly stable 120hz to use ulmb.
if you're gonna stick with gsync it will bottleneck at times, but that's where g-sync will be useful. you won't really mind fps dropping from time to time.
I do suggest an upgrade,but it's not urgent. switching to 4790k - gonna feel better at times, but I'd save for 6700k and some devilishly fast ddr4, then oc higher than your 4.3GHz, possibly reaching 4700MHz.
