Linux vs. Windows

[Michael Neikes]

As not beeing the hardcore Linux guy I ask you to give me some short
informations about your experiances.
At the moment we have a ded. Linux server and we are concidering to get
another one. Windows would be a lot easier for me to administrate, so
therefore the question.
Does a Linux Server has really so much more performance as a Win Server?
Please do not reply if you only want to say "Win sux!", or to tell me that I
am making it to easy for me.
I am just not able to have a comparison between a Win and a Linux machine
for Games (on the same Hardware)..

Thanks for your help.
