My current video card, a 256MB ATI Radeon X1900 PCI-E, is both aging and lacking support in Jaunty; most problematic for me is the almost complete inability to watch flash video full screen on my fresh 64-bit Jaunty install. I'd like to replace this card, and I'm really not sure what to go with here.

What video cards have you had complete success (i.e. 3D acceleration, full screen flash video acceleration, stability, as close to working out-of-the-box as possible) with, and what would you recommend?

I'm not much of a gamer, though I'd like to be able to fire up Civ 4 or Sins of a Solar Empire from time to time .

I'm thinking preferably in the ~$100 - $150 range, and my board is PCI-E 2.0 16x capable.

Thanks in advance for your input!
