If there is no limit in the budget, the highest price is probably the better, you know right?
But if you're looking for the best bang for your bucks in gaming, it's surely i5 skylake...

Needless to say, if there's only a slight improvement in performance, over your previous rig, then it won't be ranked high. Additionally, it's important to include mobo, ram, (plus any increase in PSU cost, if relevant), in addition, obviously, to the CPU's price. And make sure shipping costs are not too high at any of the stores you're considering.
