I am semi new to macs, i been using a g4 ibook for quiet some time now, but with this machine i would like to upgrade it. so i was wondering, can this machince be upgraded to dual cpus? or how can u tell how high u can go with the mhz of the cpu? also, i have a ton of ram laying around the house, how can i find out the what kind to put in it, like i know it is sdram, but is it 100 or 133 and whats the highest amount it will read per stick of memory? i really want to upgrade this into a pretty decent system since i can't afford to throw down the cash for a G5 *drools*

This is what the AGP supports:

RAM: 64/128/256 MB standard on 400/450/500 MHz models, expandable to 1.5 GB using PC100 SDRAM (3.3V, unbuffered, 64-bit, 168-pin, 100 MHz) in 4 DIMM slots

found on www.lowendmac.com

You can put 133 SDRAM in it, they will run at 100MHz.

thanks alot fellas, i have a TON of pc133 sdram, and i really don't mind if it runs at pc100. again thanks

I've recently upgraded a G4 AGP (450MHz) to 768MB and Mac OS X Panther...and it runs pretty smooth for it's age...
