I went out and purchased a P106-90 video card for about $70.
The card showed up properly on windows 10 and automatically installed the drivers.
Blender automatically detected the card
And it cut renders down from
1:32 to 49 seconds
Which means I was able to cut my render times in half.
Additionally, searching the blender benchmark data shows benchmarks from users with the cards p106-90 and p106-100
Note: According to some sources, the eevee render only uses the first gpu, so its likely adding a second gpu won't increase the speed of previews. Only Cycles renderer is able to use multiple GPUs.
Also these cards can only be leveraged for blender, since nvidia blocks the ability to use these cards for video games.
