I think you are asking for trouble. Tracking on a DAW is never a almost good idea. Use the DAW/Computer for mixing/mastering because when it crashes and all DAWS crash (some more catastrophically than others) you will still have the capture. By the time you upgrade with the right sound card, drivers and interfaces, you can get a decent hard drive recorder.
Here's what a lot of people are doing.
Mixcraft Sucks: Hardware Multitracker vs DAW
Here is an interesting review and op ed regarding computer recording.
Mixcraft Sucks: Why do all DAW's suck?
People have been recording on computers since before
Windows 95 and some people think it's gotten worse. On the other hand if you like solving software/hardware conflicts, workarounds, crashes, freezes,, resolving
plug in conflicts, looking for answers all day, and otherwise playing computer engineer then record on a computer but if you are serious about musical composition then you will be much happier keeping the computer out of the loop until the DAW and interface sellers and developers get their shit together. Don't hold your breath waiting for that.
