Windows 7 OS upgrade choice

[Jimbo22]

What is the difference between the Microsoft Windows Vista Ultimate SP1 32-bit for system builders OEM for $179.99 and Microsoft Windows vista Ultimate SP1 - Retail for $287.99. I looking to upgrade to vista and I'm confused as to which one I need. Can some one please explain this to me in layman's terms.
