here's the breakdown. Your PCI clock runs at 33 mhz, so at the default fsb of 100 it's at 1/3 which is 33. At 110, you're not pushing it too hard. So at the same 1/3 divider, it's running at 37 mhz. I'm sure your mobo allows for divider adjustments, so you could change it from 1/3 to 1/4 = 27.5 in the bios. I would say to leave it at 1/3. Most PCI cards can handle up to about 40 and some can go over. Obviously your cards are handling it fine if it's stable. The damage that's being done is more likely going to go unnoticed. The lifetime for computer parts is the range of 5 - 10 years, depending on the part and quality. By overclocking anything you diminish that life span somewhat but what you're doing is hardly pushing your parts. It's when you start pushing your cpu from 500-1000 and upping the voltage that really does the harm, but again, that's only cutting life in half. So my understanding is that your cpu will die, or something to that extent, in 2-5 years. In 2-5 years i won't have any of the parts i have now anyway. I hope that helped.
