I've got a 933 g4 in the garage and was wondering if there are any cheap upgrades worth doing? It has 1.25 gigs of ram, upgradeable to 1.5 so i'll do that. But a question on ram I have 2 512's and a 256, one of the 512 is ecc is there a possibility that is giving me a performance hit? This computer is only used as to listen to itunes and light surfing in the garage so I'm not expecting anything major for performance increase, but any little bit will help.
