I was thinking about adding my 8800GTS to my system to use as a Physx card. Is it worth it? I have this 8800GTS in my server, which is kind of overkill. Would I see a gain in performance by having a dedicated card to handle the Physx engine in games? Do most games use a Physx engine? I seen this article where someone had the same 2 cards I do, and the average FPS was substantially higher. Is this realistic? Also, how do the drivers work together?
Also, keep in mind, many of the lists that use PhysX, do not use GPU accelerated PhysX and do not gain anything by the dedicated PhysX card. The list that does gain advantages from a PhysX card is much smaller.
