This may be a Noob question but I noticed some people's sigs that have dual gpu and another card dedicated to Physx.
Can someone comment on the advantages of this type of setup and what it's uses would be?
It will produce roughly a 25% performance advantage when playing those games that feature GPU accelerated PhysX. In other words, you can have a single card doing both graphics and PhysX, or you can unload the PhysX calculations onto a secondary card and free up the primary card for just graphics. This will improve framerates by roughtly 25% when playing those games that feature PhysX.
