I have (3) GTX-580 Evga Classified.

I used to be able to O.C. the Video Cards to 1000Mhz Stable on Air. Since I put this new machine together I can barely hit 970Mhz without my drivers crashing. I have the latest Drivers, and updated BIOS, and I put my voltage at 1.3, which seems to be fine. Do you suggest I take the cards apart and re-apply thermal paste and see what happends?

Check your VGA temp first mate, if it's too high then you may try to re-apply thermla paste on GPU's

too bad you have updated your VBIOS, if you could to 1GHz just leave the BIOS and don't change/update it, I guess your latest VBIOS doesn't good as previous VBIOS.
