I bought a GTX 460 to go with my GTX 260. I want to use the 460 as my primary video card and the 260 as a dedicated PhysX processor.
Anyway, on my motherboard the top slot I have the 260. The bottom slot has the 460 in it. I had to do it this way because the 260 interfered with the SATA connectors on the mobo and the 460 is smaller.
However, with it set up this way if I plug my monitors into my 460 I get no video. Only if I plug my monitors into my 260 do I get video. Is there anyway to change it so my 460 is the main display card with it still being in the bottom PCI Express slot?
do this, uninstall all your drivers, remove the gtx 260, and just install the GTX 460.
Then add the GTX 260 and select it as Physx card in the Nvidia control panel, sounds like it should work, right ?
I gave that a try and it didn't work. So, I just used a dremel and cut the bottom right corner off the ginormous plastic housing that they put on the graphics card. Now it fits fine, except one of the sata cables touches the edge of the fan occasionally.
