I have a digital audio powermac g4, I was wondering which I upgrades I should do I have about 300.00 to spend, I know I'm already going to buy a pci usb 2.0, not enough usb ports, and I have a wireless card in another pci slot. So which upgrades would be the best for minimal garageband, medium Ilife, little imovie, idvd, IM, documents, ipod, music listening to, maybe a little world of warcraft (doesn't need to be superfast!) I proabably will keep the computer for about 2 1/2 years, just to put into consideration. Extra Ram 512mb Bigger HardDrive new video card dvd drive proccesser upgrade new speakers???? I didn't know if I needed a new video card, if I do which one, under 75.00! thanks for your help!
