The newer 400/500 are more energy efficient, but their core/mem frequency scaling is not implemented and they have very funny nvidia-made slowdown in specific opengl code, making card behave slower 8800.
Nvidia apparently desided that opengl is reserved for quattro and decided to castrate the driver, saying its card problems. I heared there is a workaround via cuda code.
Other than this 400/500 is definitely way to go(if you accept nvidia), except <460/560.
The card, while using above average power in idle, scales, has video acceleration and provides all 3d performance. I have not tested double dvi outputs (i dont need them).
On Amd, the open drivers do not deliver full performance, but the basic and middle gaming is covered with semi-opengl3. They have a bit more bugs in 3d, but are faster in 2d.
I dont like proprietary amd at all, people report its improved, but I dont like open/close simbitism because the closed driver loses to nvidia(the advantage/disadvantage field is very spread one, not definite), but open driver is deemed to be like second class. Of course, if you do not use discrete card for 3d, open driver possibly will cover your needs.
If you are into gaming on linux, nvidia. This includes wine. If you want to improve opensource or closed source amd driver, this means sometimes having problems (instead of working state, especially in newer hardware) and helping correct them - use amd. Sad or not, this is current behavior of companies.
