What kind of computer do i need to run tracker smooth? w/o any lags?
P4 2.8Ghz/1024MB DDR2 is it enough? and what soundcard is prefered?
your hardware is way enough.
If you use VST plugins, of course CPU and RAM requirements can raise indefinitely, depending on what you use.
A lot of us do feel that M-Audio Audiophile 2496 soundcard has a very good price-quality ratio
