What's the difference between the 675 and 680 graphics cards in the 27" iMacs?

Is the 675 still powerful? How MUCH more powerful is the 680?

Alot less than the 680mx if games are all that matters.

I guess a question for you would be: Do you play video games? I'm using mine as my primary home computer, and I don't play games... I'm fairly confident that will not change. I ended up going with the 675 and so far I'm very happy with it.

So... It all depends on what you're going to do with your computer.
