Your point #2 is especially important: with all the commotion surrounding the various "management engines" (in effect a completely independent system with privileged access to the carefully secured main system) it is surely obvious that a powerful GPU running unverified code is a foolish thing. Point #3 is also really good. Who wants to wait around at the mercy of a corporation which has an active interest in NOT being transparent about "its" IP (as speculated elsewhere most of the GPUs probably infringe on some or other patent)? Anyone buying an nvidia card for Linux should know exactly what they are doing: funding an anti-Free Software company, deeply entrenched in the ethos of secrecy, patents and bullshit; saddling themselves with a white elephant which will suck hours of their precious time.
