Dang, I have the original release XP and a SP 2 security update that runs from within that. Oh well, I just made two partitions, though I'm not a fan of partitions.
On a sadder note, I found out that even though you now have 4 DVI ports with two video cards in SLI, you can only use one monitor

You can have dual monitor if you take it out of SLI mode, but not in it

So now Stang is SLI capable, but can't use SLI.
