Two other things...

I should start this by saying that, although I enjoy editing through adobe premiere, I don't know much about computers in general

First, I checked the computer I'm on now (an older computer) and it runs on 2.66GHz. This new one I'm looking at runs on 2.4GHz. I won't lie, I don't know what that means...but I would assume a higher number is better. If that's the case...is this something I should worry about?
Also, in the event that both of those products in my first post are up to par...is the tuner compatible with that PC? I'm not exactly computer savvy...I compared the requirements, and everything seems to match up, but I'd rather be certain. I'm always hesitant to take apart a computer (especially if it's new:-p)

Thanks again!
