Is this a good buy?

I’m new and looking at buying equipment.

This has RX470 gpus, so they have been mining for 5 years

you should read this page

Ok thanks

So these GPUs aren’t listed on that page linked as one of the best GPUs. I’m thinking it may not be a good deal.

Its not. They are really old GPU’s. The hash rate most likely will barely exceed the electricity cost to run the rig.

Ok thank you for the feedback.

So what about something like this - NEW Pre-Assembled Mining Rig Kit (6 GPU FRAME , PSU, CPU, SSD, Win 10) NO GPUs | eBay

And then choosing one of these GPUs - Amazon.com : 1660 ti

Based on your earlier link and pick one.

My thought is have a GPU rig for ETH and a few ASIC miners for Bitcoin.

Whatcha think?

I dont know enough about video cards these days to help you on this.

Most of those cards in that amazon link are sold out. you are going to have a very difficult search to come up with 6-8 GPU cards of the same model and GB size.
