as seen after 825 MHz for GPU performance has ceased to grow, even more at 830 MHz on the core see failure. I repeated the tests with 825 MHz and 830 MHz - the differences were within the limits of errors
I think in DX10 frequency dependence productivity of GPU / GDDR will be similar

Same trend here with my xfire 4850's

Did some testing with these cards last night on 3D mark 06 , i ran the tests a few times with my cpu @ 3.8Ghz and as i clocked the cards over a certain point the scores started to get worse


Q6600@3.8Ghz

750/1050 = 20229
800/1075 = 21328*
825/1100 = 21199
850/1080 = 21103


Very odd, if thats the case then i might back down my 1.4v to 1.25 if its not getting me any faster speed.

I need to try it in some other games/test.
