Well just to update, college is officially Florida Institute of Technology. Army ROTC is going to pay for me as well! My major will be Computer Engineering, but I'd like to take some Electrical Engineering as well, so we'll see about that.
I talked with Praxair again, and got quoted $110 for 160L. ( $.6875/L) I'm going to rent a 160L dewar as well, for about $1 a day. Fun times ahead, this just means I need to pick up a thermos or three. I really wish I had gotten a 3930K now, but alas. I'm gonna start with the 580 on X58 first, and try out the X5570 ES on the X58A-OC.
