The Asus 7970 dc2 top is only £10 more than the 7950 you've chosen, might as well go for it. The retail CPU is £6 more but comes with a cooler(not the best but good as a backup in case the third party one fails) and 2yrs extra warranty.

Both are £20 more but modular, the seasonic is gold rated so saves you electricity bill over time.

Edit: if you can stretch to it the asus 7970 matrix platinum is £222
