I'm still using my Powermac G3 B&W at 400Mhz. I like the thing just fine, but i want to speed things up, but i don't want to waste too much cash on computer stuff. I have found this POWERLOGIX POWERFORCE G3 ZIF 900MHZ G3/ 512MB CACHE @ 900 MHZ for $250 and am not sure what to do. It is 900MHz but is a G3. I have heard the Altivec features help enhance video stuff. Would that include playing games? I would like to make this machine a better gaming mac to prove to my peecee friends macs can game too. what are the advantages and disadvantages of the G4 chip over the G3. how do you think this card would work out for me, is it worth the $$ and what kind of performance would it improve? Please reply soon, I fot invited to a LAN party 2 weeks from now and i need a good computer to take that can play some of the newer games.
