I am currently running two screens on my GTX460. Which means it doesn't clock down and i cant use its fully power gaming. I recently purchased a 8400GS PCI card to attach the extra monitor and soon another. Both cards work fine on there own, but when trying to work at the same time either i get BSOD or on the rare occasion white horizontal lines of the 8400GS monitor. Does anybody know what i need to do to get them to work together? Thanks.
