For some reason all my onboard USB has gone to hell, so I am going to pick up a pci card to hold me over until I can upgrade everything. Is there a big difference between brands? I want to just go to Good Guys or Best Buy to get it since I need USB immediately. Also, do newer motherboards come with Firewire onboard (for when I upgrade that) or should I get a USB/Firewire card now? I'm not sure what I would use it for, but I'm sure someday it will come in handy.
