long story short. without realizing i bought a gtx 460 2win (same idea as a gtx295 2 gup's on 1 PCB) i install the card both gpu's are found but only one seems to be doing the work. i read somewhere that the card needs an SLI board to use both the gpu's, can that be right? wouldn't that defeat the puropose of 2 gpu's on 1 pcb? why would a SLi board be required if the card only takes 1 pcie slot? so only 1 gpu is doing the work do to SLI not being enabled, any thought on how to get this thing to work with both gpus?
