Do you have 8 gigs of RAM laying around? 
More-
I build a few pc's for people every year learned my lesson with DDR & DDR2 I am hoarding every stick of DDR3 Ram with/without a rebate deal I can find.
Think I've got about 72 Gig's in all.

I'm not up-to-date on VP yet, does it work best with xp or xp64?
