If you're recording at a high resolution and a high framerate then you do need a powerful cpu, a lot of ram, a fast HDD/SSD to output to, preferable not the same drive that the game is on. However this is assuming that the application you're using is demanding on the cpu. Games were rarely multi-threaded until about 2007 so back then you could get away with a dual core.
