I will be honest with you. nVidia may be not the best solution (for now) for
using with free drivers, but I have an nVidia 9800GT on my desktop and an
nVidia 9600M GT on my laptop both using Trisquel and Parabola, and I have to
say that the new drivers 9.0 (available on parabola) bring a lot of cool
features and good performances (along side with the already known support for
OpenGL 3.2).
So I am pretty happy in keeping those 2 because I now that they already are a
very good hardware and since the drivers are growing fast this that in a
short time (maybe end of the next year) I will have and almost (if not
already full) experience with my nVidia Hardware using only Free Drivers :D
And this is great !
But yes, I have to admit, if you want stable and good 3D and 2D performance
NOW you need to have an HD4000 from the new intel CPU's (since they are the
best from the intel side)... They win compared to my actual GPU's using both
free drivers (not the proprietary of course).
