Shane_6 :
if it helps my current specs are:
cpu: 4460
gpu: gtx 1050ti
memory: 24gb 1600 ddr3
mobo: asus z87-a
If you aren't experience CPU limitations right now I would wait to buy a CPU. Now isn't really the best time to upgrade your CPU. Intel is coming out with 6-core mainstream Core i5 & i7 at the end of this year and that will hopefully drop the prices on the older quad-core i7.
But as previously mentioned, if you want to keep your LGA 1150 system be looking for an i7-4770K or 4790K in the used market and maybe you can find a price you like. The 4790K has been the same price used for the past 3 years so hopefully the price will drop when the next-gen comes out.
