Enviromentalists LOVE wasting electricity, look how much power an EV car takes to travel just a single mile, or how much chinese made garbage they consooom. Oil bad, magic electricity good.
The reason techspot whines about power usage is likely the same reason the rest of us do: excessive heat production is a royal PITA if you dont live in the arctic circle. (and techspot being run by environmental nuts? Huh? What on earth are you talking about, have you ever MET an ecomentalist?)
And such cards have not gone away. Look how small 3060s are. The 4200ti wasnt even the high end, that belonged to the 4600/4800, which were substantially longer, that was the era of IBM sized cards (and very loud annoying fans).
There's plenty of good games on PC from previous generations. From the current gen, Instruments of Destruction has been amazingly addictive. Enlisted has scratched that multiplayer itch, Destroy all humans 2 looks to be quite fun, We got Spiderman on PC this year too.
Gaming has always been full of detritus and greedy humans. There's still good games out there, and they're still fun to play. Just ignore the AAA trash.
In a free market we'd be free to pursue nuclear power instead of using natural gas. But hey, atoms bad, better to spend hundreds of millions on solar panels and legislate homeowners not being able to charge their new cars during the day.
Europe just made their entire grid reliant on fossil fuels from their neighbor and claimed it was "green", and were utterly SHOCKED to find out that this was a bad idea.
If only somebody had told them that....but hey, at least there are no more mean tweets, right?
