I'm considering buying a faster processor for better performance on sneshawk. But first I'd like to know if it's really worthy it. I currently have an Intel Core i5 3330 3.00GHz. Sneshawk already runs at 60fps with it, and the unthrottled speed is 120fps (2x faster). Snes9x 1.53 on other hand, goes up to 1200fps while unthrottled (20x faster). If I switch my processor to an Intel Core i7 6700k 4.00GHz, will sneshawk's unthrottled speed increase significantly? If it reaches something like snes9x 1.53 levels, then it's certainly worthy buying it. But if it just gives a small speed up, then I'd probably not bother with it. Can anyone say how high the unthrottled speed would be more or less?

Snes9x is inaccurate, so of course it WILL be faster then the BSNES Core (Either). No matter what your CPU is. In theory, a faster CPU will help. More Cores (CPU), will not really help.

mmm... I just found a comment: https://github.com/TASVideos/BizHawk/issues/432
The fastest computers in existence can only get 300% on some games. Capping out at 200%, keeping in mind bizhawk's IPC overhead with bsnes, probably isn't an issue at all.
So... in other words, no matter what I buy, I'd only get 3x at max? Not really much of a difference then since my computer can go up to 2x already.
