It really depends what comes with the engine, and how good the engine is.
If the engine comes with hundreds of universally usable assets worth $8000, then I would be willing to pay $8000 for the engine. Also the quality of the tools matter a lot, at least it should be possible to edit and create 3D models and place them around so that the engine can read it.
An engine of that price class should also support all highest-end technologies, including real-time raytracing or an alternative way to accomplish the same results. And it should run on all platforms, including consoles.
For an engine which runs on lower than GeForce 8800 cards, I wouldn't pay anything. I don't get any joy of making obsolete games, but I want to get the "wow" effect when I do some never before seen amazing stuff.
