An absolutely fantastic board for you to look for in this situation would be the EPoX EP-9NDA3I. An absolute smash for overclocking, rock solid, and dirt cheap. I love EPoX, always have and always will, I used to run nothing but because they always produced OC's for AMD's that I couldn't touch with other higher end boards. It also doesn't run any crapp VIA or ULi chipset, it runs the nf3 250 chipset so u know it's good for clockin'.
In the states it can be had for about $60 which is about ~30gbp.
