New generation? For Nvidia forget it.
My estimate is they bring the Titan first. Price 3k and up.
If we are lucky the 3080ti might come in september for
1400 EUR
i would say.
The 3080 for around 900 i think. So nothing to mine with. Much too long roi.
The 3070 could be the new mining card.... around christmas.
For AMD? No idea if they are good. I always had problems taking AMD cards to the max.
I remember with all the 480s, sorting by memory type, reselling to get good ram.... what a mess.
Glad i got rid of em. AMD has to bring out something really good if i ever buy 1 again.
I agree with you that Nvidias are way easier to handle, you can basically install the drivers, MSI afterburner and only find the better config, probably TDP, Core and Memory clocks, period.
About AMD, they are beasts in Ethash, and if people want to mine ETH and another coins Ethash, they need to face AMD and the tweaks (change bios, find a decent brand of memory, change clocks, timings etc)
For a newcomer, Nvidias are the way, but a enthusiast could handle AMD easily
About the new generation of Nvidias, no one know...they could bring something exceptional, but only time will tell...
