mobo, I merely recomended the 760G (yes right one) as its cheapest, so if it does everything you need of it then theres no point spending more, the other 2 are newer and better but as youre working on a relatively small budget just trying to save you money, theres not much between the other two, both good makes, the gigabyte has integrated gfx, if youre bothered about that, both PSUs are good, the BeQuiet marginally better, but its marginally more expensive too
