    11=SYS 7001 PCI to USB Hub Control
    11=SYS 7001 PCI to USB Hub Control
    12=ps/2 mouse
    13=Numeric data processor
    14=PRI IDE controller

    You can turn off assigning IRQ to VGA in your system BIOS, most sytems are OK with this. Unless you use USB devices, you can disable USB and other useless peripherals in BIOS too (legacy ports, etc).

    The performane hit is most likely because of the poor quality of your sound card, not the IRQ sharing.

    Try moving the sound card to a different PCI slot, this should change it's IRQ. What os are you using? If 9X you could try setting it manually in device manager or in the plug and play section of your BIOS.
