Would you invest 2000$ on a 140MH rig? Forget what the GPUs are I'm talking about MH wise, is this a good investment or a bad one?
If the rigs is pc then is worthed, if asic better buying coin then, there is no single gpu can do 140mhs at this very moment, and dedicated gpu mining from nvidia has no resale value in the future, dual rtx 3060ti or 3070ti should be fit in your budget
