I want to use Vista Ultimate 64-bit so that I can fully utilize my 4GB of RAM as well as DX10. As a person who does custom builds, I will naturally have to do clean reinstalls of Windows periodically, though the copy of Windows will only ever be on one machine at a time. Given this information, I am hoping some of you can shed light onto the following questions.

What is my best (and preferably cheapest) solution to get Vista Ultimate 64-bit? I see that the OEM DVD on Newegg is cheaper, but it says it is for system builders only (which I can qualify for), but the whole 1 install thing I hear about has me worried. Would I not be allowed to reinstall Windows on any new builds, even if that Windows OEM version would only ever be installed on one computer at a time?

Assuming the OEM option isn't viable, the next cheapest solution is to get the Upgrade option from Microsoft. What are my limitations by using the Windows Vista Ultimate 64-bit Upgrade version? I can apparently only buy it from the Microsoft website, but it's still cheaper than the full retail version of Vista Ultimate 64-bit.

Thanks in advance!
I can't help you as far as limitations for the upgrade, but i personally just recently bought the OEM Vista 64 bit from newegg.

I would think you can install it on multiple systems.

The DVD can't tell if its being installed on another system. But you are only allowed ONE activation. meaning if today, you decided to install vista64 on Computer1, but then later you want to trash Computer1 and install vista64 on Computer2, then you will need to actually call microsoft, and tell them you are installing on a new compy and revalidate ur activation. Then install on Computer2.
