Security is essentially useless? That's rich. I do agree too much energy is needed at the moment but that;s going to be fixed in time when proof of work is replaced with proof of stake.

Ok, I'm confused.  I thought this was the kind of tasks that were handled by CPUs.  Why are GPUs much better to do this?

Because newer coins like Zcash, Monero, Electronium and specialy Etherium have algoritms that were built to prevent special hardware (ASICs) dominating the network.

The good intations behind that was that any one could mine from home with out of the shelf hardware.

They couldn't forsee mining farms cutting the consumers supply of high end GPUs. 

I see..

Thanks for the info.

All you did was upgrade to a graphics card that released in 2017? That's what you did before the PS4 released in 2013?

Even before I upgraded my GPU, my PC was pushing past the Playstation 4 before it's release.

How does SLI work these days though? I read that both Nvidia and AMD silently stopped their support of it and that most developers also don't care to try to make their games take much advantage of two GPUs.

So what can we expect from new and upcoming games in terms of added performance from a second GPU?

You misunderstood. I obviously don't mean that security is useless. But having a security system where you have millions of GPUs that calculate artificially very complex and extremely computation-heavy calculations is useless and a huge waste of resources, when a similar and a perfectly adequate level of security could be achieved with a regular security system that only requires a few computers.

Just another reason why I still prefer console gaming.

Consoles aren't immune to component price increases.
