Hey. I'm looking for a G4 upgrade processor for my Blue and White G3 300. I recently upgraded it to 640 MB of RAM and I just purchased a 64MB Radeon video card for the Mac. I'm looking at upgrades from Fastmac, Sonnet, Daystar, Newer Technology, and Apple themselves. I was wondering if any of you who have used these upgrades in the past could tell me how each of them worked for you. Thanks! ^-^
