I doubt that's true. I have several Stretch installations with old GeForce gfxchips.
These two hosts have similar in age to the 7100: 8400GS roughly a year newer, 6150SE,
roughly the same age (series is older, but specific chip was released 6 months after
the 7x00 series was initially released).

I suggest you try:

1-purge *vidia* and everything directly related to proprietary driver installation
2-purge xserver-xorg-video-nouveau
3-ensure libdrm-nouveau2 is installed
4-ensure there's nothing left to update from Jessie to Stretch

There could be other packages never installed or upgraded to Stretch from Jessie, but
since I have at least two GeForce oldies working, I'd think you should be able to too.
The Xorg nouveau might work, but I've had no reason I can remember to try it on these
two hosts.

Note that my installations all use Trinity as Xorg's DM and default DE.
