What's up fellas?

I'm looking into buying a new PC, which I intend on using primarily for the following...

1: Downloading/burning music
2: Typing class reports
3: Video editing
4: Watching/recording television

Myself and some friends of mine have been making some short videos recently and I love the filming aspect, but I'd like to be more involved in the editing process. I've also seen Windows Media Center recently, which I think is neat as well. It would be convenient for me to be able to watch television while working on a paper or whatnot, as well as being able to record things if I'm not able to watch them live.

I was looking into getting a Dell computer...but the cheapest one I could scrounge up that met what I'm told are good video editing standards was about $850. Needless to say, I'm scrounging money for tuition so every penny counts.

Now I saw a commercial for some circuit city PCs...I log on to the website and find this...

Now bear in mind, I don't need a fantastic editing suite...I'm just looking for something that I will be able to edit on without any tedious slowdowns due to the computers hardware, and something that can handle the installation of a tv tuner card for watching/recording television (which is an additional $95 http://www.circuitcity.com/ssm/ATI-H...oductDetail.do).

All in all...if this can work for what I want...I'd be coming away spending $200 less than I would with Dell...and that to me is a tremendous chunk of change. So what do you think...would this be a wise investment for my intentions?

Thanks for any thoughts/opinions!
