I set myself up a system on tigerdirect for about $1700. Still debating on if I really do NEED this upgrade (I WANT it

) as that's a lot of money and I'm saving up for a house.
8GB of ram, 2TB raid 5 (capacity for another 2TB raid 5 array) Intel Core 2 Quad, case, psu, whole shebang.
My excuse is career advancement. I'll need that server so I can setup complex windows VM environments so I can study for my A+, MCSA/E and possibly other certs like Linux+ It will also have production VMs and the host itself will be prod.
OR do I want till the 8 cores come out?

Decisions decisions.
