I picked up a used 32core 128gb server for $1000 recently... It's only a matter of time before these 1080 will be sold for pennies on the dollar.
If your lively hood doesn't depend on it, wait.

Gamers are complaining about why can't nVidia just ramp up their production. Having worked in a Fab and an assembly factory, there is a tremendous amount of coordination that needs to happen. Let's forget the business aspects for a moment - in order to ramp up production, it is not just building more lines. Silicon industry supply chains are mind bogglingly complex from oil-free-air supply hardware, etching chemicals…
> Gamers are complaining about why can't nVidia just ramp up their production. I don't see too much of that in gaming circles. It's understood that it would be risky as crypto will crash sooner than later. The anger in the PC community is almost exclusively directed at miners. Threads about it pop up on the daily, but what can we do? We could lobby NVIDIA/AMD to somehow implement restrictions on what the Gaming SKUs…
I wanted to buy 2 1080 for deep learning experiments, but that's going to have to wait. I picked up a used 32core 128gb server for $1000 recently... It's only a matter of time before these 1080 will be sold for pennies on the dollar. If your lively hood doesn't depend on it, wait.
What would happen if Crytpo booms big time?

ASICs aren't saving the planet either - people are incentivized to burn up to $BLOCK_REWARD of electricity per block, the number of hashes it takes to do so is irrelevant. If you come up with a better ASIC, people will buy more of them, the network difficulty increases, and you're back where you started. It's just another stage in the Red Queen's Race. The only thing ASICs do is centralize control (because economies…
Though there is some benefit to cryptocurrencies that rely on ASICs for mining: it means that someone with a significant amount of CPUs/GPUs under their control (such as botnet operators, or government groups like the NSA) can't waltz in and trivially 51% attack the blockchain with their existing general-purpose hardware, and then go back to using it for other things. An attacker would have to commit to buying/buildi…

Is Cryptocurrency a form of entropy exchange from Energy (increasing entropy via heat) to information entropy (decreasing information entropy by hashing)? I am thinking more broadly in terms of thermodynamics. I understand classical Thermodynanamics but I don't understand information entropy well. From the standpoint of physics, Energy is the ultimate currency and it seems like we are trading it to decrease informati…
Of course there is some connection, but the simple "exchange" you're looking for does not exist.
Maybe there's something I missed about GPUs and mining, but how can an amateur rig like these hope to keep up with ASIC rigs? Can you profitably mine with residential electricity and GPUs still? How long can that possibly last?
It's great. Once ethereum etc. crash we can buy used high end graphic cards cheap.

I'm legitimately worried about the long term future of my hobby (PC gaming) at this point. Prices like this have a cascade effect because when less people can afford to build a PC and/or upgrade there's less incentive for developers and publishers to spend time on the platform. Consoles are shielded by the ability of Sony and Microsoft to take losses which will be absorbed by online fees and higher game prices but no…
> Consoles are shielded by the ability of Sony and Microsoft to take losses which will be absorbed by online fees and higher game prices I imagine they are also shielded to some extent by being AMD APU-based, so the market for discrete GPUs has less of an effect.

Proof of work is about consensus among mutually distrusting parties. It has approximately nothing to do with entropy. Of course there is some connection, but the simple "exchange" you're looking for does not exist.
Think more abstractly - at the end of the day, Energy is being consumed to compute some problem. That solution has intrinsic value precisely because it took energy to solve it. Extrinsic value is the market economy of CC, and that's where the 'proof of work' and 'consensus amongst distrusting parties' comes into play - that concept of a currency is only valuable if sufficient number of parties agree to its value. I am weeding into the underlying fabric that holds Crytocurrency together.
Imagine if Energy was free, despite of 'consensus', the supply of such currency would be virtually unlimited and it would be worthless.
