My nVidia past away last week (RIP) and it had been a long time I was looking for a new AMD card.
I want to change to AMD mainly because they are sharing their cards specs, and I want to encourage this kind of initiatives.
But also because my old nVidia card died thanks to the open source drivers that burned it at 120C.

I know nVidia is the safety choice right now, but hey! I'm an adventurous guy
The problem is that I'm a bit lost with the numbers right now...
I heard the 7000 series aren't supported by the open-source drivers, is it still the case?
If it is, I was considering the HD 67xx or 68xx. I don't know the difference between a 6750 and a 6770 though...

Do you think it's a good move ?

Thanks for your replies!
