It may be true that gNewSense 3.0 currently is more stable than Trisquel (although Trisquel 6.0 is base on a Long-Time-Support release of Ubuntu and I have not had any trouble with it yet). However, Debian "oldstable"'s base for gNewSense 3.0 will stop receiving updates next year. Probably by May. Given the (very) long time it took for the gNewSense project to release its 3.0 version, one could worry that no new version (based on Debian's current stable release) would be available by then. If that happens, the user who cares about security would have to switch to Trisquel (or any other other GNU/Linux distribution that still receives proper updates).
The only graphical chipsets that optimally work with Linux-libre are Intel's.
Everything needed to drive them (including firmware) is free software
provided by Intel itself. I believe AMD mainboards only accept AMD processors
with no integrated graphical chipset. You therefore need a video card on top
of them. Both AMD and nVidia cards can be plugged. Both will give you a
display with free drivers. However those free drivers do not offer as many
functionalities and as much performance as the proprietary ones (that you do
not want). This is particularly true for AMD video cards that lack some free
firmware to enable 3D acceleration. The situation with nVidia cards is
better. 3D acceleration is available for some of them. You can even obtained
performances that are higher than those provided by an Intel chipset (but the
price is not the same!). You however need to inform yourself to know what
specific models provide good performances with the "nouveau" driver. One of
them is the GeForce 9500GT and is sold by ThinkPenguin:
