Is pci express an new type of physical pci slot, or can you just plug in a pcie video card to your pci slot and you're good to go?

Nevermind, stupid question.....
Yes PCIE is a new type of Physical PCI slot. There are two new types of PICE Slots:
1) PCIE16x - for Graphic Cards
2) PCIE1x - for PCIX (modem, sound, network, and RAID) cards
You can put old PCI cards in the PCIE1x Slots, I sure that you cant put PCI Video Cards in the PCIE16x Slots. I hope this has help you some to understanding PCIE.
