Ah, I forgot to post my results.
I usually run my computer with high-speed, turbo boost etc disabled, basically, always in "low power" mode. In this I get 120 frames per second (exactly, that's not a rounded number). When I enable all those things, as well as run it with my powerful video card rather than the built-in weaker (but less power-intensive) one, I get 239 frames per second. 17 inch monitor in 1366x768 resolution, and my computer is a laptop if that matters. It's a Core i7, I forget the exact model but it's a quad-core 2GHz, and I have 4GB RAM, no idea what speed the RAM is.
