AMD has a perfect opportunity to pair or outperform Nvidia - this launch is very important and they need to win market share with gamers. Nvidia clearly was pressed with this launch; using samsung, large tdp, paper launch (basically). RDNA2 will very likely be power efficient...AMD is going to have their hands full balancing miners and gamers
that is why i didn't recommend getting 5700xt, if the new amd cards pair with 3080 performance you'll have old tech cards LOL.
I still see 2x 5700xt as a better choice then 1x 3080
but marginally.
Basically I can find and buy 5700xt for 360usd plus tax.
If I could get the blower style 3080 in a few days I could pay 650 plus tax.
as i can get ten percent off newegg. but the problem is I cant get those 3080s anyplace.
Since i am making 1 dollar or so profit on the 5700xt and have mined them for over sixty days. many days i made 2 dollars on them. so 70 x 1.50 is 105 . so if i paid 385-105= 270
vs zero earned or spent since no 3080 to buy.
At current rate my cards will pay off in jan or feb.
the 3000 series clearly is not more efficient
the 3000 series would be cheaper per mh if I could have purchased them.
so for now mine with what i got.
