Some would say even today that it was NT4 that was the pinnacle. There are many things that can be said, but indeed Win2k was a hog compared to NT4 while being a fairly modest improvement (despite all the new features like Active Directory).
Nowadays I only run Windows 2000 in a VM, and CRT refresh rate is no longer a concern, it may be worth considering going backing to NT4, as I'm pretty sure I can set the background to the warmer W2K gray in NT4. Thanks for the idea!
