It usually depends on if you are going to the same chipset, i.e. Intel to Intel. Most likely and to avoid headaches I would advise you just to do a fresh install anyway. Which TB drives did you get? I saw where ZZF had 16MB Hitachi TB drives for $69 after a $10 MIR. Figures, seeing as I spent $99 a piece for mine ~ 3 months ago, though they are the 32MB variety.
*EDIT*
Which P5Q did you get?
