Can someone look over this gaming pc and tell me if it's good enough?

Looking for a powerful gaming pc. I'm kind of new to this, and don't know much about specs. So here it is, what are the basic things i need to look for? My budget is around £650, 700 tops.

Can you look these specs over to tell me if they're good enough to play games like minecraft (with the highest settings), Skyrim, battlefield 3,4 etc?

Yeah, it's a decent PC. If I were to change one thing it would be Windows 8, can't bare it… But over all a decent set-up and you'll be able to run most if not all games on high-ultra!
