Thanks all for your info.
Since my intent is to learn but also to replace win xp (I finally
decided to migate to a better OS), I will be amking use of this PC for
most of my work.
I gues for now I will go with a dual boot install, install FC4 and try
it out. If it seems to buggy I can always continue to work in Windows
until upgrades to fix those bugs come out.
Thanks again to all.
