thanks for the replies.
I guess the question I am trying to ask is do you need to buy different software for the 6t4 bit thing or does 32 bit software work?
The older I get the less time I want to spend learning how to do the same things over again.

What I'm looking for is to replace my xp media center computer that is having problems. The system I'm talking about has the built in tv card so I can use it as a personal video recorder to record TV.

Normally I wouldn't think about it but I saw a good price for what looks like a lot of machine.
