I have the GF7050v-m7. I wasn't really able to tell a functional difference between the two either. I recommend the one I have. It has quite a few options in the bios, takes to pin mods, and so far has been a fairly stable board.
Does anyone know if this is a hard and fast rule? Why wouldn't one support the entire line of processors? I just bought the SE version and would hope it will support any of the stated processor types, but then again, I'm more familiar with AMD and have never run into this before on the systems I've built. Thanks!
