After reading Tom's review, I was sold on the the Radeon AIW. I want one for editing and it seems the way to go for video quality.
The V7100 is very fast in gaming, but the AIW is the way to go for video editing.
A lot of sites reviewed the AIW, but most just benchmarked it for gaming, not video capture. Tom's article was very informative and he shot camcorder footage to compare the two, and AIW won.
A very good site I found where a lot of AIW users go to is:
Rage Underground
Lots of info, reviews, and tips from users like us.
