the problem with pci is that you will run out of bandwidth very fast... its 133mb/s shared on all pci slots... so if you have 2 pci->pci-e adapters, max teorical bandwidth for each card is 66mb/s

As far as I know PCI is faster then PCIe x1. But never the less, since when is bandwidth a huge factor in GPGPU work?

Bandwidth really doesn't lower hashrates?

Not at all. Mining on PCIe x1 is like mining on x16. You can mine even with USB if you have the controller, but it's not worth it since the price is very high.
