[Q] Question about Running emulators with slimkat with all f2fs support topic

I was wondering if anyone knows what effect it has on gaming performance, specifically how does GPU over clocking compare to CPU over clocking with emulators like epsxe,Dosbox turbo, recast...etc. I just rooted my n7 for the first time and this will be my first flashed ROM so noob doesn't even begin to describe me. Still, I was just wondering if anyone had experience with it and would emulators got off of Google play even work on since from what I read you need slim gapps instead of the others, though those are Google proprietary apps. Could any one help me out?
