If you want to continue with that card you'll want to make sure there is an available slot for it (PCI I believe)

You may want to weigh the option of 64 bit vs 32 bit. Check the available drivers for that soundcard; see if Win 7 64 bit is supported. If not check Win 7 32 bit. This may be a big deal for the soundcard. Do a little digging for reported problems just as a precaution.

Otherwise, I suggest at least 4 gig RAM, and also at least a dual core processor. If you plan to use firewire in the future check that it has that, and hopefully a TI chipset, as this brand seems most reliable.

As a side note, I like having the HDMI port for larger monitors, etc. It is very handy here. The number of USB ports is to be considered also, as these fill up fast.

I do not work here, but the benefits are still awesome
