How about a combination of existing benchmarks. Would not be hard to combine a couple of apps, with a taskmanager screenshot showing them running simultaneously.
Something along the lines of a memory dependent of a memory dependent CPU benchmark, like spi32 combined with a 3d app that is not as CPU dependent. OR Develop a loader that sets affinity for each so if you have a dual core or quad core your can assign one or two cores per application.
If we are talking about making our own benchmark, which seems to be how this is headed, I have some other ideas that I would be more comfortable discussing in a more private setting. Seems to be a unique idea, and would rather not have the idea taken
