It's an OLD ass CPU. You know this.. you're just being stupid. You can get a 6700k on amazon for about $300, and it DESTORYS that shit CPU.
These aren't expensive things.. you don't need TONS of cores. CPUs these days run at 2x the frequency of that old hunk of junk, as well as performing way more instructions per clock. The fact that you're running the emulator mostly fine on such an old shit CPU speaks volumes as to how you don't need a monster CPU. Get with the times lol
