Hey everyone. I've got a Dual G4 867 stock, except for no modem. *grin* That means 512 RAM. I also have an external 80GB Lacie D2 firewire HD.. and a Radio Shark USB 4-port hub, haha. Ohhh, and an HP Deskjet 960c! Er... a Microsoft Intellimouse Explorer Trackball.. some dust.. Anyway. 512 ram, right? Now I do a lot of audio work, and I mean a lot of audio work, and I also run a Carracho server full time. Two actually. Often when doing audio work, 100MB of RAM can be taken up just by audio files. I'm running Cubase SX, Max/MSP, Supercollider, Csound, etc... and usually not all at once. So I am thinking, 512 - 250 for audio - 150 for the OS leaves me a spare 100, right? Or does X use more than I think? 512 DDR2100 is only 70 bucks.. should I go for it? Would it improve speed at all, or would it not be noticable? Sorry if this post is duh-tastic, but I've been up since, Sunday... and its Tuesday. Eep.
