Halo, Has anyone try to install 2 ATI 3870 as crossfire for Asus M3A32-MVP motherboard and running at 16x speed at the sametime? If so, please tell me how can it done? Coz in the manual, if i install PCIe slot 1 running 16x, as for PCIe slot 2 running 1x that if i config as crossfire mode. Any help???
