Tools for simulating "normal" load on Windows Server?

I'm trying to convince my boss that enabling features like VT-x in our virtual environment will provide us a real world benefit, and he wants graphs and numbers and all that Chief Exeutive level stuff.

I've already begun monitoring metrics for a few low priority test machines, but my plan is to spin up a test VM and simulate a "typical" workload for about a month both before and after making the proposed changes.

I'm hoping there is a tool similar to stress-ng but for Windows that I can set, for example, a somewhat variable load for CPU and RAM that centers around about 50% resource usage.

A combination of tools is also acceptable, I was considering memtest + prime95, but wanted to see if there's a better way. Disk IO simulation is less of a concern but if that's in there too, all the better.
