Yeah, reading it back 30 minutes later, it seems like a stupid question.
In part it's to avoid future temptation; recently went from 2x1GB to 2x2GB RAM, now going from C2D to C2Q, and that's it, no more upgrading on this board (apart from graphics in the future, 8800 still holding it's own). Thought about just getting the Q9650 so I wouldn't have that voice nagging me further down the road...
I really should see a shrink about that voice.
