I'm curious, for my new build should I spend the $200 on the retail version of Windows 7, or save some money and get the OEM version?

The only difference is the licensing. Functionally they are identical. The retail version is "portable" meaning you can move it to a new computer while the OEM version is only good for the first computer you install it on. This gets a bit fuzzy for us enthusiasts since we tend to replace individual components rather than replacing a whole rig at once. Changes like a motherboard swap can cause Windows to deactivate but a call to Microsoft can usually straighten this out.

So it really comes down to how you intend to use it and ethics. When you call Microsoft to reactivate the automated system will ask you how many computers this copy of Windows has been installed on.

On a side note, if you intend to install more than 16GB of memory like some folks on this forum then you'll need to buy the Professional or Ultimate version. The Home Premium version only supports up to 16.

I guess it is all up to what you are planning on doing with the system and how long you intend to keep the system. Or if you will ever change to Win8

Thanks for the info. I don't plan on changing my rig anytime soon and I rather doubt I'll be switching to Windows 8, I really don't like it. I'm only going with 16GB of RAM so I guess I'll stick with Home Premium.

I'd get something other then home premium. I'm not sure how windows allocates your sticks of ram (16 gigs) and the ram of your gpu
