That looks pretty good. The screen resolution is a bit high at 1080 (ideally, you don't want the native screen resolution to be too high, since for games to look good, you want to run in native resolution for the screen - it's a lot easier for a mobile graphics car to drive a game at 720p than 1080p), but that's not a huge problem unless he wants lots of MSAA )
I'd also seriously think about swapping out the 1TB hard drive for a 128Gb SSD. The upgrade is only £5 in options, and does mean storage is much more limited, but in games and general use the lappy will be MUCH faster.
