They work good and stable on windows, gamma ray takes around 5 minutes. It is almost exactly the same as the normal w5700 in performance only way lower wattage, 80-90watt in comparison to 140 on the w5700.
Its funny because the fans on the cards stop spinning and start up because core just remains around 50-60 degrees max while the w5700 runs around 70+
In comparison my a6000 runs a gamma ray in 2 minutes so in comparison to that its not that impressive.
But still the performance per watt is really great, also why it stands out in mining.
I have build a rig with one w5700 (for display out) and 3 BC-160 cards. Windows just says it's 4x w5700.
Gonna let it run for a couple of weeks and see where it ends in the top 50 machines.
Also looking around to a reliable way to hookup additional gpu's with bifurcation (have 6 bc-160 total), but physically space, riser and extension cable reliability remains troublesome to get x4x4x4x4 gen four from a slot to gpu's nearby

I decided to check out the prices on EBAY of the AMD BC-160 and they are in the $1250US to $1639US range to 'buy it now', I think that puts them up into the serious cruncher phase right now but if as you say they start dropping in price they could be decent buys as long as they aren't nearly dead from mining too fast for too long.

I have had mixed success with using riser cards with a 1 to 4 expansion port and 1 to 8 expansion port. With a Threadripper you should have enough lanes to make that work. Gen3 is fast enough for E@H processing.
If another MB has more than 4 16x MB that would also work. If any MB also has some 1x slots you could use high quality ribbon cables to move the 16x slot gpus up onto a mining frame and use the 1x slots for one GPU a piece. Which might be more reliable.
A 4 GPU rig will already make you highly competitive.
Because I had so much trouble trying to run Ryzen cpu's with higher than 3 gpus I have been experimenting with a fairly low cost EPYC Motherboard solution. A 7 slot solution that works with ribbon cables. If you want to throw enough money at it you can get a gen4 7 slot solution.

For me money has always been the limiting factor in the way I accumulate stuff to crunch with.
