Huh, I don't notice our bill changing much from when I used to turn the computer off at night vs. leaving it on 24/7. So it just stays on all day and night now.
Sorry, I was in a rush when I wrote that. I'm using the Folding@home Windows Client version 5.03. I set the core priority to the slightly higher option and I upped the CPU Usage Percent to 100%. I left all of the other settings on default.
