Re: Mining difficulties when Ethereum goes to POS - What are you going to do?
I'm in ETH since 2016 and I kinda miss those good old days with 2 mined coins a day 
. I've started with R390's and R370 rigs.
Today I've one A10pro 500 5GB and still some old 13x RX480 (8GB versions) running - nearly 1GH/s. I'm going to replace them with RX 5700 or 6800 soon.
Here are some specs of the A10pro+ - which is actually a "customised GPU miner": https://www.whattomine.com/miners/126-innosilicon-a10-pro-6gb
With 1300 watts @ the wall their new 720MH/s version is not much more efficient than the 500 MH/s A10pro. Its like 1.9 watts/MH versus 1.8 watts/MH.

You think it's worth the time and money to build a new GPU mining rig dedicated to ETH still?
Boderline. A lot depends on the deal you make.
A 6 card nvidia 3080 can do just under 600mh if you spend under 4k maybe it is okay.
https://www.innosilicon.com/html/a10pro-miner/index.html. here is an a10pro 4400 add shipping and trump tax it is over 5500
If you could get the nvidia 3080 at 700 a card (good luck). that is 4200 add 400 for other parts you are at 4600.
I would rather the nvidia rig at 4600 then the a10pro at 5500.
Eth has been going pos since 2016 it is 2020.
Like I said name a good pos coin that held value for 2 years and paid 5% interest. I do not know of one.
So I am betting that eth does not go full pos.
Besides I need 70 days to pay off all the gpus I got in July.
