Hey guys, not sure if this is a Gigabyte issue, but I thought I'd ask here anyway.

I've got a 5870 and I'm trying to install an Nvidia GTX 260+ card to try out the hybrid PhysX mod.

I have the 5870 in the primary PCI-express x 16 slot and the Nvidia card in the bottom slot (x8 slot).

I've followed this guide :

"Assuming you already have ATI card and drivers installed:

1/ Stick in your Nvidia card.

2/ Download Forceware 258.96 and install it.

3/ Restart.

4/ Install hybrid 1.04ff."

When trying to install the Nvidia 258.96 drivers it keeps saying compatible hardware not found.

I thought maybe the card was not seated properly so I tried re-seating it and the fan on the card seems to be spinning so it shouldn't be that.

I don't think it's a Gigabyte issue, but I thought I'd post and ask here in case there is a setting in the BIOS I need to change on the UD7 to get the Nvidia card working? It doesn't seem like it's detected. I would have thought that it would show up in GPU-Z even with out drivers installed, but it doesn't. Only the ATI card is listed.
