I will be building my first gaming desktop in about a month and need help with deciding on a cpu. I know a cpu doesn't add many FPS on games, but I will be emulating games as well. Such as on DeSmuME, PCSX2, and Dolphin. So which cpu would give the best performance for emulating between ivy bridge, and haswell? Originally I was going with the i5-3570K and I plan on overclocking the cpu I get to 4.2-4.4GHz in the future.
