Looking to upgrade my CPU

[Leomanof1000]

I want to upgrade my 860k, but I don't know what CPU to get. I do know that I'll need to change motherboard. I want to know if I should go AM3+ or go Intel. I mostly use my PC for gaming. Don't have a limit on budget.

There are no AMD processors that have a significantly higher single thread capability than your current cpu.
Few games can use more than 2-3 threads.

Your upgrade should be to Intel.
If you have no budget limit, buy a I5-6600K, a Z170 motherboard and plan on a modest overclock.
That is as good as it gets for gaming today.
The fast core speeds will be particularly good for strategy games, sims, and mmo types.
