I've got a nVidia 8800GS and have had no issues with 14.04. I had a lot of
issues getting it to work initially on 12.04 a couple of years ago (me just
learning at the time probably) but since getting it working I have moved up
through 13.04, 13.10 and then 14.04 just using standard upgrade with nothing
special (that I recall). For me it is rock solid.
