"OWC -- PowerLogix PowerForce Series 100 G4/1GHz (1000MHz) Upgrade with 2MB Cache for Apple G4 Cube Models. 2yr PowerLogix Warranty. (PLGPFG41000C) ......$599" Now THAT is a much better price! All my $$$ is spent (for the next few months) on x-mas gifts, but by the time I can afford these again, I'm sure they'll be even cheaper! The main reason I was going to upgrade was for games...but I bought a Game Cube for $125 instead, along with Metroid Prime (coolest game ever!!!), Star Wars: Bounty Hunter, Star Wars: Jedi Knight 2, Mortal Kombat: Deadly Alliance, Maddens 2003, and already pre-ordered Zelda: the Wind Waker all for less than the 800MHz upgrade (rebates, free controllers, free carrying case, and $70 worth of discounts at best buy), and suddenly I don't care much about GeForce 3 cards, 1.5gb of RAM, processors, frames per second, heat, etc... All I've had on my mac for the last 3 years was Quake 3. I love my G4 Cube, but I've come to the realization that gaming was meant for consoles (except in the case of Quake 3 Arena). My Cube now does work/internet only...and does it well at 450MHz. Games, like Jedi Knight 2, are SMOOTH AS SILK! A constant 60fps, with much better detail! Plus, you can get consoles shaped like cubes (and in different colors...purple, black, and platnium)....with PowerPC and ATi chips even!! Nintendos Game Cube is almost worthy of Apple's logo....considering it's biggest competitors are sony and microsoft even ;) jesse .
