3570, MSI Z77a-GD45/55/65.
If you're buying soon, http://www.overclockers.co.uk/showpr...odid=MB-199-MS
that is a very good deal.
Then your choice of case,
Corsair CX 500 / 600 power supply.
Then dependant on whether you want an SSD, you could probably squeeze out a 7850 for gaming. Otherwise a 560ti will do fine.
