Please help > Kernel Panic / Mac Pro 4,1

Hi All,

I need help.

I'm getting a lot of seemingly random kernel panics about 5 times a day. Doesn't seem to matter what I'm doing, Email, Facebook, Photoshop, Illustrator, Coda, Terminal etc.

I have a sneaking suspicion it may be the video card but don't have the technical chops to confirm.

Below I've posted a couple of the kernel panics, I don't know how to read these things any help or insight would be really appreciated...
