It would probably be cheaper getting a P3 if you are going for a KT7. It is an expensive board.
BTW running a Quake server on DSL = useless. Its good for playing with a few friends but that is about it.
Most high bandwidth users ie me

set there rate to 10K+ some use the default setting of 25K. You really think that with 10 people playing your DSl line can sustain 250K/sec?
I have experimented with high speed DSl and cable connections and I have personally found that it can't compare to a server setup on a college campus
