thx guys for the quick replys, couldn't think of what the game capture software nvidia used was called but will be using shadowplay, game wise will be for mainly for Project Cars(pCars) which will be doing most of the recording of, Battlefield 4, COD: Black ops 2/Ghosts, AC Black Flag, Crysis, Tera online, WoW which will also be recording, will be a few other games but for now these are the main games im playing.
Also will a 650w PSU be enough?
