I run a triscreen setup (top half is split into quarter screens, bottom half is a single screen for my main) and i have the top two screens nerfed on gfx, bottom window on balls out gfx. Top half of the screen is set to one processor, bottom to another. I noticed no serious FPS boosts. The only thing that i did notice was that when mousing from one of the quarter screens to the other, there is usually no "mouse hang" when crossing the border. Since the bottom screen is on a different core, there is always a slight hang when crossing the screen's equator.

When i have the processor affinity set to auto i get mouse hang at every border regardless. Anyone else notice this?
