The only things I'm interested in is price and availability, everything else is a very, very distant third. Rumours of faster memory and a higher TBP (whatever that is) doesn't even generate enough interest in me to read the 1st paragraph of the article.
20W on average, not a big deal. But, what about potential spikes in that power draw? We've seen some articles that show that some of the newer cards (example 3080) can have big spikes in power draw. That's a question we won't be able to answer until we get cards that we can test with.
