DESPITE WHAT people were claiming, the G70 will score better than the 7800. The card never got the 7800 suffix based on its 3Dmark05 score and if it was number would end up significantly bigger. It's actually going to be quite better but still not as good as the "Fudo" R520.
We got some numbers from this card and it turns out that R520 scores more than 10000 in 3Dmark05. We still don't know its clock speeds but we know the score. For what we know Nvidia can not mach this with G70.
