Guide to G3 Daughter Cards

Got a Power Mac or compatible? Join the Power Macs email list.

Effective 12/31/98, this page is no longer being updated. Please see the new Guide to G3 Daughter Cards that uses MacBench 5 ratings. On average, MacBench 5 processor scores are 5-10% lower than MacBench 4 scores, since they are benchmarked to a different baseline computer.

Note that computers upgraded with these cards may not support Mac OS X when it ships in 1999. (Apple has emphatically stated it will run on all Macs designed with a G3 processor, but has never promised any support for G3-upgraded models.)

Be sure to read That extra 10% to help you decide which upgrade provides the best value for you.

* Processor score from MacWeek or Macworld when possible, but many MacBench ratings are from manufacturers. End user results will vary based on a number of factors including bus speed and OS used.

** Estimated value is MacBench rating divided by price. Figure is based on estimated MacBench score for untested cards. Higher numbers represent more bang for the buck.
