Hi there,
Tell the group more about your system to be, CPU, RAM, Video Card, Modem, Audio Card, Network Card, PSU, etc. That way everyone can consider the same problem and come up with the best solution.
This board has a nice Audio system built in, as well as a Network adapter. You should be using a PCI-e Video card with this MB.
If you have a PCI dial-up modem, or PCI audio card, purchasing one with a PCI-e connector could make it a lot faster and solve the problem.
Or, if you absolutely have to keep your 2 PCI cards, possibly a different MB with 2 PCI slots could be recommended.
