I usually just leave my PCI-e bus at 100Mhz but I did try 105Mhz for a few months but I truely didn't notice any difference? I have researched in the past what the benefits might be of increased PCI-e bus speeds but don't remember exaclty what they were (if any)? I suppose that any benefits come in when running cards at the edge (maxed out clocks or what have you)?

Eldonko - Great work there but is there any chance you would share your GTL settings with us, especially since you seem to have found a decent combo of settings?
