Like bacon said not actually a very good deal.. The 5770 is poor by todays standard.
The Z77M is a decent board but lacks overc locking abilities eg voltage control. A bit of a waste on the 3570k really, not worth it.
I would say it is decent for £50, he is getting it almost half price...lol. Full price? Nah the regular D3H is better.
The 5770 might be pretty meh but it will get him by for a month then he can get a B grade 7850.
EDIT: The board does not support overclocking AT ALL? is that true?...
