(OWC) has begun shipping an 800MHz Mercury Extreme G4 processor upgrade for US$269.99.
OWC’s Mercury Extreme processor upgrades are compatible with Power Mac G4 AGP-equipped models (350MHz to 1GHz) and act as replacements to the stock Apple G4 daughtercard. The upgrades don’t occupy a separate PCI or AGP slot nor do they require enabling software. Included in each upgrade is a pre-installed heat sink and a cooling fan.
The Mercury Extreme G4 processor upgrades feature 256Kb of 1:1 L2 cache on-chip and 2MB of L3 cache. They’re compatible with Mac OS X and Mac OS 9.2 and higher.
