Anyone else running a single stock AMD Radeon HD 7970 GHz Edition GPU (Gigabyte) GV-R797TO-3GD?

if so, what Mhash/s are you pulling?

any tweaks or recommendations?
Not interested in OC figures or multi-card set ups.. just single card stock set up.

I'm at 649 Mhash/s using guiminer... extra flags: -f0
