Ok, So my current everyday machine is a G5 Dual 1.8ghz maxed out at 4g of RAM. Today I found a G5 Dual Core 2.5ghz that can run up to 16g RAM for only $65.00. So I know I cant run any better than Leopard in either machine, and the G5 I have now has been pretty reliable for my needs, so is the speed bump really worth the money? Will I really notice a difference or would I be throwing money away on a system that in the end, is just as dead as what Ive got? Thought Id ask for some opinions.
