I'm having some problems with my 3870. I was benching 985/2700 with vgpu mod and after a reboot I got no signal on my monitor.
I moved it to the second PCIX slot, plugged in a 6200TC in the first PCIX slot and it was detected in Windows. Gpuz detected the 3870 fine, the only strange issue was that the GPU load was at 99%.

The question is what's the problem? Video card 'almost dead'?
Any chance to be fixed somehow?
