The only other card in the computer is a PCI network card on the PCI
slot farthest from the AGP. The sound is on the motherboard. The video
card is using IRQ 16, which is shared with the network card (can't
seem to change IRQs). Benchmarking was done while not doing any
networking, internet, or anything else.

2 cards, and plug & pray decides they should share an interrupt!! that
sucks
