The benchmarks shows the SIS chipset to be very stable. Also this board and/or chipset isn't made for people that want to put in there own sound, ect. Thats why it is all integrated. Buy a Asus or Abit or something if you want your own hardware. 2 pci is plenty for the buget people happy with the sound, video, lan card, 56k modem, ect that comes on the board.
