Vectordash needs x8 PCie 3 with 2 cores per GPU and lots of system ram. Pref 250gb fast NVME drive. System needs to be online 24/7. I have had a 1080ti and 1070 on a I7 7700 system with a 256Gb NVME drive but after 2 weeks got zero payment. Also no one rented the VMs so Im not so sure they have any users. Vast.ai needs little less. X4 PCIE and one core per gpu and 30gb per gpu. I have a 4x1080ti system on a MSI z270 Carbon Pro so mine is at x4 PCIE. BUt its been a few weeks now and my system still has not been verified. Also I find there docs very lacking and almost no help on there tech discord. Im thinking of putting a dedicated golem.network host online.
The 15 Mbit/s download (per GPU) and 40 Mbit/s upload (per GPU) is a limiting factor for me although this may not be an issue for some people. Most people with mining rigs will have to upgrade their motherboard and cpu in order to make this work for them. From what you are saying it sounds like rentals could be very sporadic and your system would just sit idle most of the time until someone rents it.
