I tried GRID Demo.. Everything seemed to go alright. I maxed out the Graphics at 1680 x 1050, and had my GPU load hit 80%. WIth a GPU Temp Memio of a Hight of 80C.
Anyone tried this demo and could let me know your performance at these settings with a 4870? My card is supposed to me 9% faster then average 4870... so it says..
