As the title says... Should i SLI them or dedicate 1 as a physX card?

Keep them in SLI. The benefits in non-PhysX games are obvious, but the benefit in PhysX games will outpace the performance of using one as a dedicated PhysX card. Just set your PhysX setting in the Nvidia Control Panel to 'Auto' and let the software engineers decide.
