I'll third the MAC thing, once you go Mac, you won't go back!
While I love Sufentanil (the drug silly!) I must encourage you to go bigger than 20", I use the Apple 23", which is 1920x1200 and it does well for me on those multi site days.
I once again am in envy of Albert Porter's toys, I am debating buying the 30" monitor he has, but to be honest I doubt I, or you CW would need that much real estate, Albert does a lot of photography work and obviously needs the space, on my 23" I typically have several apps running multiple items per and can easily navigate them all on the 23"s I have, and yes the 30" is ~$1K more...
