Best PSU + GPU for less than £230

[JDSjoel]

Upgrading my GPU which means I also have to get a new power supply as it is unbranded.What would be the best pair to get, I only care about gaming performance and don't mind about power consumption . I also do not have a preference of AMD or nVidia and crossfire/SLi is not a option because of my motherboard.
