The Presonus you indicated is a really nice soundcard. You will need a Texas Instruments Firewire chipset to avoid problems with firewire. This is not to say that other chips haven't worked but most have problems. The easiest way to tell is to open the computer and locate the firewire chip on the motherboard and look at the mfg.

But one of the best bang for the buck cards is a Delta 1010LT for multitracking. Good solid drivers and since it's a pci card, low latency. Under $200.
