The E250 can take up to two peocessors. As far as which processor you should get, you do not have a choice since the E250 architecture does support different CPU's. All you have to do is find which processor you have and buy a second one (refurbished from SUN are much cheaper). You can get the CPU speed with prtdiag Too bad I.T. is not cash business
