That was my thought too.

I have to be careful where I spend my money... so one thing at a time. 
What I have is already a very big step up from what I had.

PCI bridge: Intel Corporation 8 Series/C220 Series Chipset Family PCI 
Express Root Port #3 (rev d5)
00:1c.3 PCI bridge: Intel Corporation 82801 PCI Bridge (rev d5)

I am not sure which is which. The first may be the express port.

Most of my MB manuals so far have had nothing and so I have had to try 
various slots and see what I get. In any case cat /proc/interupts tells me 
I have two clear irqs for my two PCI cards.

I have no PCIe devices at this time.
