I think this will be a bit difficult what GPU is the best to buy for a free power source you must only buy the cheaper one or used to reach the maximum profit.
Check this tool for a list of GPUs that are currently profitable https://whattomine.com/gpus change the power cost to 0 to sort all power-hungry and profitable GPUs. And then look for sellers who sell them for a cheap price.
I hope that this is your daily free power source.
Topic: Which GPU with 3Kw free energy to use? (Read 145 times)
hmm.. none, get a G1-mini asic and pocket the remaining 1.6k eur or get multiple units (120w*24=power use per day). As in my sig..
Please do not try to use a GPU to mine Bitcoin. Funds an asic that suits your needs!!
There is no need for warning this person because its not going to work, you make it sound like trying it will ruin the GPU instantly lol, the only way to get Bitcoin using GPU is getting paid in Bitcoin mining other altcoins like Ethereum, Ravencoin or Flux, another good example is Nicehash.That's what I mean! I can pay less for a GPU and use the free electricity on other algorithms getting paid in satoshi on nicehash...it is a way to stack sats with free energy and sounds me not bad...

Have you forgotten that bboyem16 only has 2000 euros?
It can only make the most of the free electricity when you buy used graphics cards. After the end of ethereum mining, the profit of RX 470 4 GB and 6600 will be the same on many algorithms, so he better not take new video cards now. Or make purchases after the completion of ethereum mining.

pny rtx 3060 two fan model is a decent card
amd 6600 are okay
amd 6600 are okay
Now that LHR is out of the way I would also suggest RTX 3060 dual fan any brand,but mostly find the one which is cheaper because in mining it does not matter if it is Gigabyte,Pny,Galax or any other brand,they all offer the same hash rate.You can start with 5 such cards and get a 250 Mhsh rig and since you don't pay energy it will be a good card with 12 GB of memory capable of running many algorithms to suit your needs even when Ethereum mining ends,if it will end on September like most people are predicting.

It's no more about which graphic card you will use, it's now about how much you will get them, are graphic cards cheap enough in your country? If yes then go with those that have higher hashrate less power consumption for example
1660 supers.
3070
A2000
RX6600XT
1660 supers.
3070
A2000
RX6600XT
Fallowing that everything on amd side is good choice, exception of the 6900xt
6600 6700 6800 will bring you 0.6w/h rate
If you want to go dirt cheap and full that 3k go used and maybe cheap 570 will do,30mh for 90w
If you want to use almost all 3 kilowatts for 2000 euros of investment, then you need to buy RX 470 4 GB graphics cards and mine ethereum classic or Ravencoin. This money may be enough for 2 mining farms with 8 such video cards, but it depends on the prices in your country.

I dont see where op said anything about mining Bitcoin.

Hi guys...I'm pretty new on mining subject. May u suggest me pls which is the best quality/price ratio for a GPU to buy or maybe a little mining rig? I have 2000 euros to spend in GPU and 3Kw free energy from home photovoltaic. Thanks in advance to whom would like to propose some solutions =)
