1 gig it is

and it s not really about the speed of the machine the blue G3's have a 100 mhz bus

but about pumping too much money in old tech to keep it modern while modern better technology is availble for less money

yes he can up grade his memory to the max ( which can be expensive a 512 mb pc 100 module is 103 euro here ) plunk in a better video card and a monsterous cpu upgrade but even then that machine will never be able to stand up against a G5 tower or imac which are now both dirty cheap even cheaper then the combined price of all those upgrades

so more ram better video card ignore the cpu upgrades unless you have a bottemless wallet
