Got my second 7900GS in the mail yesterday, heres the results
These are de-badged Gainward Golden Samples and overclocked from 450/660 to core/mem to 645/765.
The one I bought first would happily bench at 650/800, but the second refuses to budge from the above stable speeds... which is rather annoying... but still, im not complaining at a score of over 12k in '05!
Will post up scores in Hwbot threads and run e-penisMark'06 later.
