I just did a test, using MSI Afterburner to monitor my GPU, and Windows Resource Monitor to monitor my CPU. With Minecraft, Firefox(20-30 tabs), Mumble, Steam, Skype and OBS running, my GPU usage was at 18% use, and my CPU at 22%. When I start recording with OBS, GPU usage dropped to 2%, and CPU usage jumped to 40%.
My CPU is an Intel i5-4690K, and my GPU is an AMD Radeon R9 270. I'm running Windows 8.
