Well, your speedier bus (which also adds that .067MHz processing advantage), and additional RAM likely prove to be the edge: Overall: 129.65 CPU: 168.68 Quartz: 171.10 OpenGL: 136.03 Your video card surely outperforms when it comes to groovy, flyin' 3D squares (probably rocks with Quake, too), but a bit clunky with the real world Quartz action. This is with my $120 Radeon Pro 9000 video card, BTW-- rest of the specs below. --- c
