I can't see myself over clocking the system by that much at all (if i even attempt it!) so am guessing the choice between the two coolers won't make that much a difference in the long run considering all the reviews stated the difference is down to a couple of degrees at best 
The final spec was:
MSI ATI Radeon HD 6950 OC Twin FrozR III Power Edition 2048MB GDDR5 PCI-Express Graphics Card with FREE DIRT3 Game
Intel Core i5-2500K 3.30GHz (Sandybridge) Socket LGA1155 Processor - OEM
MSI P67A-GD53 Intel P67 (Socket 1155) DDR3 Motherboard - (Sandybridge) ** B3 REVISION **
Corsair Enthusiast Series TX 850W V2 High Performance Power Supply (CMPSU-850TXV2UK)
G.Skill RipJaw 8GB (2x4GB) DDR3 PC3-10666C9 1333MHz Dual Channel Kit
Cooler Master HAF 912 Plus Case - Black
Corsair Hydro H60 CPU Cooler with free Akasa Apache Fan (Socket LGA1366 / 1155 / 1156 / 775 / AM2 / AM3)
Samsung SpinPoint F3 1TB SATA-II 32MB Cache - OEM (HD103SJ)
LiteOn IHAS124-19 24x DVD±RW SATA ReWriter (Black) - OEM
Antec Tri-Cool 3-Speed 120mm Fan - Black x 3 (i got the fans to play about with the cooling)
All came in at a tad over £840 which leaves me a little bit left over to maybe look at adding an SSD in the future (i know nothing about SSD's)
