What is it exactly a processor adds to games? I'm just curious, I really don't know.Not worth it in the slightest... well, actually worth exactly in the slightest. Not worth the money. Save it for something where you'll see significantly more improvement. Either load times with an SSD or a GPU for much better value. i5 is perfect for gaming.
I guess I could upgrade my GPU from a GTX 780 to a newer one next year, or maybe just HTC Vive.
More games are going multithreaded due to the PS4 and XBO including multicore x86 jaguar CPUs, and DX12 should see more efficient use of those cores.
Yeah, that's what I'm thinking.
