I have an HD 4670. It still works like it did when I first got it. Open-source drivers are pretty good for that card from what I'm reading here, but I'm running Debian Wheezy, and don't want to go into testing or unstable, because that's made a big mess of things for me before.
I always ran Catalyst on it since I got it in late 2009. One bug that never got fixed was: X11 would sometimes freeze when I tried to wake xscreensaver. l also could never see the unlock-screen dialog box-the screensaver would just stop, and I'd have to press numlock to see if it had locked up.
And it stuttered in games.
I bought a used Geforce 6800 from an electronic junk store for a different computer, and installed nVidia's legacy drivers. Acutal computing experience was comparable to superior to the HD 4670, outside of modern games.
The difference was the reason I went with a GTX 770.
It's using nVidia's very shiny (expensive!) reference cooler, and is very quiet. No, that's not a mistype: the GTX 770's reference cooler is actually very quiet until the GPU temp goes above 80C (after which it's still reasonably quiet), and most of the heat goes out the back of my case. Of course, you can drive the blower faster by enabling Coolbits, and it won't be quiet for you if you do that.
The big thing I don't like about the 770 is this: if your desktop isn't OpenGL-accelerated, it will tear things like window moves and browser scrolling.

You also have to make sure your movie player is set for OpenGL output, or it will tear your movie something awful.
