Latency question. Please help. :)

OK. I'm a new user here and this is my first post. I've just gotten into recording and am having some issues with n-track.

I have just started using the trial version of n-track and I am havinf latncy issues when I record multiple tracks. I recorded a drum track first and then, whenver I try to record a guitar track to go along with it, it is delayed. Now, my setup isn't the best, but I think it should work for what I'm trying to do right now. My equipment is as follows:

P4 1.6ghz w/512mb RAM
Aureal Vortex Soundcard(not near good enough, but I just started this today)

Behringer Eurorack 1604A Mic/Line Mxer
Zoom MRS-4 Digital 4 track
Zoom MRT-3 Drum Machine
Johnson J-Station

Various mics, guitars, basses.....

Can anyone provide me with some tips on how to conquer this latency issue?

Thanks!

Ok...never mind. I got it figured out.
There was a huge (and ever increasing) lag due to the crappy nature of my Aureal Vortex soundcard. Ipopped a SB Audigy from another computer in there and it solved the problem.

Now, my problem is deciding which sound card to buy....
