i have a g3 desktop given to me it came with 9.2. since then my nephew gave me an upgrade to osx works better but freezes alot and trouble with java etc he told me i would need to soup up the ram etc.so i could down load the new stuff and to go here and ask for advice so here i am this mac is a spare for our house so i can get access to web craigslist ebay i don't play games but i do use some video and digital pics so can i keep this mac as a toy with bargain upgrades it seems quite obsolete to put much cash into seeing a new pc with faster speed can be had in the three hundrud range,can i buy memory on the cheap used?thanks
