Edit: Just saw something I didn't catch before... The computers you build for others is not a licensing violation; the 3 you have are unless you bought them with a piece of qualifying hardware. If you purchase just the OEM software without any qualifying hardware and install it on your own computer, that is a violation according to Microsoft.
Please don't mistake my posts as judgement of any kind, they are not. I only posted what I had read and my interpretation of the licensing. The reason that I hadn't bought the OEM in the past had to do with what was said about the upgrading which I have never tried. Personally I have never liked the upgrade disks that they sell... I hate having to use 2 different disks to install 1 operating system.
I will make sure in the future that I purchase hardware that comes with the OEM version which solves any issue I have personally.
As far as the mobo, I wasn't actually going to upgrade the system when Bulldozer comes out. I was going to build another new system and buy one of those expensive techno-whiz-bang boards that they have out. Building another AMD Thurban now and then Bulldozer later would give me the 3 systems that I would like to have and a place to install all of the GPUs that I have laying around.![]()
