Who is buying these things at 800 dollars? At that rate why not go with a 1080 Ti? The Vegas are only amazing at Cryptonight from what I can tell. Almost a cryptonight ASIC as a mining card...
Why wouldn't they? A modified vega gets double what a 1080ti can net you in returns. Even if it's cryptonight/ethereum only there are these things called Exchanges where you can then convert to your coin of choice. Not sure if you've heard of them before.
Double? Where are you getting that from?
It's about the same from what I've an tell and the 1080 Ti is much more versatile.
If I could get a Vega at MSRP that would make sense but right now the 1080ti seems like a better choice than an 800 dollar Vega.
Also, of course I know about exchanges. The point is your profitability is tied to a single algorithm and depends totally on coins with that specific algo being profitable when you swap them.
What to mine actually has the 1080 Ti at 14 dollars a day profit vs the Vega 56 at 10 dollar per day over the past 7 days profitability.
