My mobo does support Sata III. I'll be using this SSD for boot and a game or two. I'm also not sure if I can reinstall Windows 7 (I have an OEM builder's version, can that be installed multiple times?) so migration software included would be a plus. But ultimately, I'm looking for the best performance/$. Again, thanks for your guidance.
To answer your second quetion you can install the win 7 OEM version multiple times. It is just tied to your mobo so if you get a new mobo you will need a new win 7 key. I was able to activate my win 7 oem edition 2 times on 2 different hard drives within a matter of a few weeks so you should be fine.
I had purchased an OEM version of Windows XP pro 64bit and I reinstalled it multiple times on different motherboards and hdds. The process is different from just installing it and putting in the key code and clicking enter and it does it automaticly. What happens is it comes back with can't authorize it and you need to cakll this 800 number , which is an automated process of giving your set of numbers to the computer on the other end and then getting a set of numbers back which you have to enter. There was even one time when I actually talked to a live person and all she did was ask a couple questions abouit the situation and then gave me a new key code.
The Windows software is something that you purchased not rented so you should be able to change the motherboard , the hdd and anything else you want without haveing to buy a new OS. It's different of course if you were building computers and selling them but your not.
I guess there are some loopholes in the system but OEM is meant to be tied to 1 computer and Microsofts definition of computer is the mobo. If your mobo breaks you still have the right to use that copy of windows 7 but I think if you just choose to upgrade your mobo its technically breaking the user agreement. Will Microsoft know or do anything; probably not, but that's how a OEM license works.
