Actually, there is a small advantage to being able to handle background tasks when running Dolphin. In general, quad-core+ systems often experience minor boosts in performance (5% sounds right) over comparable dual-core systems when it comes to Dolphin. It's small enough to be insignificant practically, but objectively speaking having extra cores/threads around does help. If you believe the OpenMP texture decoder is anything but a placebo, then you might get speed ups there as well.
