I use a flock of Mac Minis as servers. Most if not all run headless. In my experience Finder operations and other apps seem fine. But I seldom if ever run anything terribly graphics intensive.

At least in the old days, Macs would turn off the GPU when no screen was attached, meaning that you'd end up in software emulation when you did any openGL calls. I thought that was different these days, but maybe this reminds you of something you're doing that could cause this slowdown?
