Dug through it and it looks like my school is part of that, so that'll save me $100, hopefully.
So, done with most of my researching and this all looks pretty damned compatible. Decided to go with 4GB of DDR3 2000 rather than 6 GB of 1333 or the 1066 stuff. Dunno how big of a performance change that would make but I will add more RAM later on. I did notice that with that board I lose speed with every stick of memory I add over 2 but I imagine getting a mobo that allows 2 GHz for 4x2GB sticks wouldn't be that cheap.
