yes, i'm building it by myself, but i wrote i'm buying it, sorry!
i will not play multyplayer a lot, and mmo neither. i'll play games like cs:go and tf2, gta and mostlu trials evolution. but i also want to play next gen games good. i think i'll take the amd solution, it's cheaper and better than the intel solution. what about the psu, is a 550w enough?
