For all the people asking "why?" It's the same reason people pour money into home theater, cars, or any other hobby. People do this because they enjoy it.
I like to have the "perfect" setup. Of course, that definition is relative and ever-changing. In reality, I end up spending an insane amount of time adjusting, switching to different software, or trying to get the last 1% of a feature working. It's not always enjoyable :-)
