Powermac G5 Quad

Apple quietly rolled out a Powermac G5 Quad with dual-core PowerPC processors. Yeah. Crazy. (Of course, if you bought it from Apple with the full 16GB of RAM, dual 500GB harddrives, and the best graphics card it would cost you around $18,000. Plus peripherals. Plus software. Yeesh.) Can computers really get much faster than they are now?
