I was a beta tester on the VFX-1. A 17 year old boy's dream come true. I got a choppy 20 fps playing Descent on my Compaq 486 66Mhz with 16MB RAM. I dont remember what video card I had, but in order for it to work I had to remove the cover of my PC and plug it in directly, as it wasnt yet working with VGA cables. Good times.

The article states it retailed for $200-$300, which is inaccurate - I remember it costing about $1000. Sadly I was not allowed to keep the beta unit.
