OWC expands Mercury Extreme G4 Processor Upgrade line

Other World Computing (OWC) today announced it has expanded its Mercury Extreme G4 AGP processor upgrade line with the addition of a 1 GHz model.

The addition supplements one of the most complete collections of processor upgrades available in the Macintosh market. The new processor upgrade is available immediately through OWC for only $349.99.

The OWC Mercury G4 Extreme line offers cost-effective, easy to install plug and play solutions to increase the performance of Apple PowerMac G4 models. Requiring no software enablers, OWC’s Mercury Extreme processor upgrades are completely compatible with all Macintosh software and operating systems. Additionally, these upgrades can make it possible to utilize certain application features or run entire applications that require higher processing speeds than many stock processors provide.

“With products like our Extreme G4 line, upgrading an existing PowerMac can be very cost effective,” said Larry O’Connor, president of OWC in the press release. “Not only do our upgrades offer a significant performance gain for the software you run now, but they even allow features and software to be utilized that would otherwise require a new system altogether. All in all it’s an option that is definitely worth consideration when an older Mac can run like new again for just a few hundred dollars.”

The OWC Mercury Extreme G4 processor upgrades feature 256 Kilobytes of 1:1 L2 cache on-chip and 2 Megabytes of high-speed SPD or DDR L3 Cache operating at up to 267 MHz. They are compatible with Apple PowerMac G4 AGP Graphics (Sawtooth), Gigabit Ethernet, Digital Audio and Quicksilver models and support Mac OS 9.2.1 and higher, as well as OS X and higher, including all 10.2.x versions. Each Extreme G4 processor upgrade is backed by a three-year warranty and a 30-day 100 percent money-back guarantee.

“Not only are we pleased to introduce the 1.0GHz upgrade, but we have reduced the price of our Mercury Extreme G4/1.3-1.33GHz card from $529.99 to $499.99,” O’Connor said in the press release. “Other World Computing is all about always providing the best products at the best value possible.”

  1. When are these going to support the Blue & White G3s? I have a 450 G4 in it now, which is close to the best I can get. I’d really like to pick up a Ghz or 1.25 Ghz to extend the life of this machine.
