My dual PPro 200's run NT 4, the dual PPro 333 overdrives run Win2k. Why would you run XP on a dual processor system?
In my case the answer to that is because I was running a high-end 3D and video editing workstation, and needed the extra "umphf" that only a dual-socket rig could provide. It turns out, when you use an application that was designed to take full advantage of multiple CPUs, it runs like gangbusters.
”Shines” is an interesting word. I know it’s heresy to say anything nice about any version of Windows newer than XP (or is it 7? I keep losing track), but the one thing that actually impressed me about Windows 10 was how much more responsive the UI is compared to any version I remember going back into the 9x era…
I've actually had the exact opposite experience. Like completely 180 degrees.
Lately I've been running "retro" LAN parties with a combination of new and old PCs. Since the "new"-ish systems run modern hardware, I fairly routinely wipe and re-load Windows 10. Fresh, out of the box, without network connectivity, it feels like I'm wading through cement. 10 seems to have some stupid background process it feels is MUCH more important than the UI actually being usable.
Compare to a windows 98 or hell even Windows 7 fresh install. Both are zippy as can be. Its such a weird feeling to load up windows 98 for the first time and actually be able to use it. I keep my daily driver windows 10 PCs running 24/7 because I know every reboot comes with 30+ minutes of sitting there letting the thing think about being a computer before it lets me work.
As far as "shining", I'm not talking about the UI. I'm talking about being able to use the system to its fullest potential. The Core2 Duo, even with the exact same clock speed, is just better than a P4. The available RAM is faster. A Geforce 8800 can run circles around even the very fastest AGP cards(I think they made some AGP 7800s, but they were trash?).
When you add it all up, if you have nostalgia for the Windows XP era, you want a later machine. It does everything its predecessors did, but better.
