Just my opinion
EDIT: If you still want to get more out of your card, try dropping the core a little (700mhz ish) and raising the memory OC.
Thanks People great advice! Will try 450*8
Regarding lowering the Shader clock, they seem to be linked, the more I lower the shader the more I have to Lower the core clock, even if I use Riva Tuner's 'Unlink frequencies'. - Am I missing something?
