Sure. And of course, any corporation who hires highly paid qualified professionals will also get them rusty cheap tools to save money
No, they wouldn't, but they wouldn't overbuy for the job either. For most workers an i5 in a tiny desktop is more than enough. For the bosses, an i7 and 16G and 32G RAM, for IT, i7, 32G RAM, though I do have my own resources at home.
There is *nobody* in the building that would benefit job-wise from anything faster. People talk about computer performance, i.e. cpu and arch around here like it's everything, but just about everything that's well provisioned is faster than a worker can work these days. Obviously anything that needs lots of CPU/GPU needs more, but *most* people don't need that in places where I work these days, and nobody does where I currently work. Not a discrete GPU in the building...
