i just got my FSX back up and running

hello,
I just got a bigger HD (320 gig) and loaded FSX back onto my comp. Last night i added SP1 to it and was thinking about added SP2 but will it work with my video card? It is the BFG 7950 GT OC running DX9. Is SP2 only for DX10? And if i can run SP2 what are the advantage's over SP1?
thank you
