The alignment "stub", called the key, is what differentiates 3.3v cards from 5v cards.

PCI Express is the correct answer to your question. The newer wave of motherboards has a slightly different form factor and your old card may not (and obviously does not) fit. My last new compute, AND the one I built myself, both have only 1 conventional PCI slot, and I used that for my dual head video card in both of those systems because nerd boy has to have dual monitors.

Another example of why I hate onboard cards vs outboard. A nice M-Audio Fast Track Pro would cure all your ills.
