I am currently planning on an aMD based XPC. Between the SK43G, SN45G, and SN85G4v2, all have their own combination of features and affordabilty, which is key. I heard the athe SN45G can overclock, but is it worth trying that with an XP-M, sticking with the 333fsb limitation of the SK43G, or drop the change on the SN85G which is currently running the Nforce3 150, a chipset that is already doomed for replacement by the 250 some say......ideas?
