I'd basically just go for any Asus board depending on budget: under £100, the 970 EVO R2.0. £100-£130 the 990FX Pro R2.0. £130-£160 the Sabertooth. £160+ the Crosshair Formula Z.
The only other one I'd consider is the cheapy Gigabyte 970 board with VRM heatsinks which was recently updated, it's about £60 and is fine for running at stock clocks, so is a decent budget option.
