You can get a GTX 1060 or GTX 1070 (if your budget allows). 4690K is a powerful CPU due to its 4 Powerful Cores. If you're gaming at 60Hz (which you've mentioned) then no, it won't bottleneck any GPU. AT 144Hz though it may slightly, just slightly get under pressure in games such as Battlefield 4.
An i3 in this case will bottleneck a GTX 1070 due to having only 2 Cores in it.
