So i want to buy a Nvidia rtx 3090, could someone tell me if it matters which type you buy if you also want to mine altcoins with it? Or give some tips?

If you want to buy a RTX 3090 be aware that it consumes a lot of power. If you mine ETH it consumes around 290W at 121 MH/s so if you want to have a mining rig with 6 X RTX 3090 then you'll need to buy at least 2 PSU of 1300 W so it's much more expensive.

Compare to that, you can have 6 X RTX 3070 with only one 1300W PSU because each 3070 consumes around 115W at 62 MH/s on Ethash.

Also considering presently (May 21th) you can get a RTX 3070 on Ebay around 1,575 USD and for the
RTX 3090 it's more around 3,975 USD - 4,150 USD.

So as you can see the RTX 3090 is more than twice the price of the RTX 3070 but in fact on Ethash the RTX 3090 is (in average) not more than twice the hash rate of the 3070. So in my opinion the RTX 3070 is a better investment to mine ETH also the efficiency (hashrate per watt) is better with the RTX 3070. Here's a link to the topic I started about that on bitcointalk:

except he can buy a 3090 now. my card is set to 284 watts and does 113 mh steady quiet and easy

this is the 2 of them

What do you mean philipma1957 when you wrote : "except he can buy a 3090 now?".
You can buy RTX 3090 and RTX 3070 now on Ebay or Amazon except the price are crazy for the RTX 3090.

Furthermore your RTX3090 does 113 mh which is not even half of the average 62.37 mh for the RTX3070.

He is in europe and stated he could get a 3090 right now. At a decent price.

He did not mention he has access to 3070 gear.

So he was asking If people thought it would be okay to get it.

personally I think it was an okay deal for him.

Not good not great but okay.

The listing he linked was from a retail seller so he would get full warranty. and it is the exact same evga I have which I know does 113 endlessly with out an issue.

That is what I meant. I do agree with you that in a world where he gets 2x 3070 for 1300 euros each the same 2600 euros that would be better off assuming the seller is legit and he gets a warranty.

But he never mentioned he had access to 2x 3070 pieces for 1300 each.

Okay got you!
