Debian questions

[db at epsi.net]

Hello all,

I am getting ready to switch from Mandrake to Debian, I am fed up with 
no being able to do things
my way and Mandrake was good to start with but I feel I am ready to move 
on. I just switched from
MandrakePPC to YellowDog on my Mac and I am very satisfied.

I have just a few questions before I jump in:

1. Will debian support my ATI Tv Card
2. Can I run KDE, Gnome, Enlightenment etc.
3. Are most Linux apps ported to Debian

If there is a place online to research this I will be glad to find the 
info myself but I seem to
be looking in the wrong places so far. Thanks ahead for the help and 
input that I am sure
will be posted.

Dave
