Are you sure you're going to be using that much power or is this one of those "I've got to have the most powerful box I can get" kinda things cause trust me, I've done that.. but I've realized its better to just get something you need rather than trying to max out everything
Spending all that much just doesn't seem logical to me.
Anyway, to answer your question, yes, it seems like a good rig to me. I'd invest in a BD drive if its cheap and you plan to use this PC for 4 years or so with no additions. Or you you just get it in a couple of years when it becomes main stream
