That statement is a myth. I had a fujitsu 1.76Ghz PC with 1Gig of Ram with a Radean video card in it with a 15" true color screen. I play World of Warcraft and the PC would lock up horribly and crash me out of the game. I have a 15" G4 Powerbook with the same Ram and it works flawlessly. I've even forgotten to close apps like messenger and mail before going into the game and I've never crashed on my Mac.
