PCI based GPUs?

[BkkCoins]

I have a few older PCI only main boards. I thought maybe I could get them working a bit.

I know the better, new GPUs aren't going to work but is there any older GPUs that use PCI that I might pick up on eBay perhaps that could contribute, say, more than 10MH/s each?

Or are they pretty much all useless today?

Even if you could get those types of cards, it would not be worth it to mine that slowly. The only way I know that you could use those slots is getting the PCI > PCI-e adapter that Cablesaurus sells.
