I do some beta testing for MS & w8.1 is cracking now a days. you can tweak some parts of it to make it feel more like w7 but it is good out of the box. Intel for me nowadays too as I was a AMD man many years back, but Intel have got a cracking over clocking cpu called the intel Pentium anniversary ed g3258 what you can get to a good 4.30 GHz easy even on air. it was in pc format & I got one for a client of mine & tested it so I know it can oc ok even with a cheapish mobo. when I get 15 mins I will draw up a few rigs for you, but what are you using the pc for if I may ask ? games, 3d art drawing, music etc etc. kenny
