Question

Answer 1

No, you can't install a 16x pci-e card on to a PCI 64bit. It's totally not compatible, even physically. A 64bit PCI slot is at least twice as long as a 16x pci-e bus and the pins arrangement is all different.

Answer 2

No. There is very little similar about them. I was in the naming meetings and argued against the name PCI express as it is very confusing. Apparently my argument was a bit confusing too. I lost :(
