So I have a G4 533 Digital Audio. It treats me fine, but I am interested in adding some pep. Here are my specs... G4 533 GeForce2 MX 768 MB RAM 120 GB SATA HD (added recently and love the speed increase) So I don't want to spend a ton of money buying a top of the line CPU upgrade. I was hoping to buy a CPU from an older Mac. Maybe something along these lines. Would getting a Dual 533 be worth it? http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=80031&item=5724030721&rd=1 Would a CPU from a Quicksilver work in my Mac? I also want to get a better video card. What is the best card I could get where I wouldn't be overdoing it. I remember someone saying that anything beyong a GeForce4 would be too much for the system to use fully. I would like to be able to take advantage of core video when Tiger comes out. Any thoughts?? Thanks!
