Firstly welcome as i can see it is
your first post 
What ever you do,,, Do not buy gateway media pc's, I know that the are giving free plasma TV display screens with there pc's but still dont.
I used to have one and i sold it, There media pc's itself needs improvements on the os, Buying a media pc from gateway will be waste of your money... I would like to point out that you will save some gas bills thought, gateway pc's can help
heat your house in the winter and its load humming can scare household pest.
The only thing good about the one that i had sold was the
great 42inc plasma tv display screen, it really do have sharp graphics, NOTHING ELSE was good.
