I still prefer PS2 mouses & keyboards.
Modern fancy stuff. Far to easy to plug them in the wrong port, unlike the proper originals.
9Pin Serial Mouse and AT Keyboard. All industry standard at the time..... oh how things have changed.
GPU pricing is solely down to Cryptocurrency miners.
Only if you listen to (notoriously lazy) computer journos.
Whilst the crypto-miners have had an impact, you'll find most are going into data centres and supercomputers.
Data centres don't tend to have a huge array of GPU performance, for obvious reasons. Supercomputers, yes, but they are not as prevalent as people make out. The *new* big thing in PC gaming was going to be Cloud Gaming.... it never really took off, and big names in the industry have since dropped plans to expand, or indeed scrapped what they had already implemented.
Seriously, cyrptocurrency mining is MASSIVE, and only getting bigger. You only need to look at the number of new currencies which are being
made-up on the spot sold as the next BitCoin. Serious money is being spent by the Energy companies, as Electricity theft is a huge problem, and not for growing Herbs.
