"Would simply getting a nice sound card and an expensive set of head phones cure the problem of having poor pc speakers for editing?"
well, yes and no. a good set of headphones is certainly better than a poor set of speakers but there are a few catches.
headphone are very good with mid-high frequency response and very bad with low frequency despite numerous psuedo enchancements so you will never get real world sound although you will certainly get a good idea of the s/n ratio.
the other thing is that headphones generally target just one ear (L&R) whereas in the real world there is some "cross correlation"(can't think of the actual proper term for this at the mo) between the two because speakers do not target the ears specifically but rather the entire room. there have been attempts made (some very good ones too i might add) to simulate this in headphones but they still just haven't hit the mark and i personally don't think they ever will..
so to answer the question, headphones are far better than cheap speakers but still won't match up to a good 2.1 setup.
