I have a mining rig with an older motherboard that only has 4 PCIe slots. Rather than buying a new motherboard and cpu, I was wondering if I could use something like this to add more PCIe ports.

Has anyone used these for this purpose? Are there any issues using them? Do the cards still hash at full speed or does the expansion card slow things down a bit?
Looking to pickup a few more 1080Ti off ebay while prices are cheap, and don't want to have to build a new rig to run them.
