I currently have an i5-4460 with an ASRock H97 Anniversary MOBO and a GTX 970. I want to upgrade my CPU. What are some CPU's that are compatible with my board that would be noteworthy upgrades over my 4460? Something overclockable for later on down the road is also preferable but not a requirement if the base speed is fast enough. The only CPU extensive thing I do on my PC is game.
