This is what i'd call "decent", but in actual fact this is probably one of the best overclocking boards on the market (and it better be for £100!).
If we take a step away from the bleeding edge and look towards the 965P Chipset-ed boards we find some nice buys, ie the
Gigabyte S3, which is just the Gigabyte DS3 (Great overclocking budget board) without the solid capacitors (which saves you £7), unfortunately with the new P35 chipset out, the 965's aren't selling as well so the prices are going up...
This image might be of use, even if it is a little outdated (no P35 boards), replace "Enthusiast" with 1337z0r overclockz0r and you get the idea.
That eVGA 650i board might be one of your best bets
