Is my GPU and motherboard ok?

[Userremoved]

After recently trying to add a PhysX card into my new PC

Spoiler

(which failed)

I tried to find similar issues with my motherboard and GPU and I found one similar issue (http://www.overclock.net/amd-motherboards/786992-cant-get-9800gt-working-physx-asus.html). Since I own a 5770 (he had a 5870) a M4A89GTD PRO/USB 3 (he had the same motherboard) and a 9500GT GPU (he had a 9800GT (from my old PC)) and I did the same things he did (more or less) like install my ATi GPU in the 8X slot and the 9500GT in the 16X slot and vise versa and Windows also did not detect the 9500GT. I got worried about two things:

1. Is my GPU getting full 16X bandwidth (http://s919.photobucket.com/albums/ad38/Userremoved/?action=view&current=Untitled.jpg (GPU in the 16X slot))?
2. Is my motherboard working correctly or is the chip set creating the issues?

Is my motherboard broken or something or is it true that motherboard does not support two GPUs from both ATi and Nvidia?
Any help would really be appreciated

NVIDIA drivers do not allow physx when an ati GPU is installed. I think there are some hacked drivers or something though.

What I mean is Windows did not detect it at all.

But still from the picture can anyone tell if the card is running at 16X?
