So Borderlands 2 is releasing soon and I want to take full advantage of the PhysX of this game. At the moment I'm using a EVGA Nvidia GTX 560 1GB. I'm looking to buy a decent priced card to use as a PhysX slave that won't cause bottlenecking. Was wondering if the GeForce 9800 GT would be a good pick or should I go with something higher priced?
You need to max out your CUDA cores to get the best PhysX performance in a dedicated card. Be sure to look at some of the new low-end 600 series, like the GT 640, which has 384 CUDA cores and costs less than $100.
On a game like Borderlands 2 that uses Physx, can a single card provide the same experience as a lesser card with a dedicated physx card? I have the Gigbyte GTX670, I would assume it would be powerful enough to max the settings and also handle the Physx related processing or does it truly require a dedicated card???
Ehh sorry, might have hijacked somewhat. The OP does not have a 670, I have a 670 and was wondering if you actually needed a dedicated Physx card to take advantage of Physx. I am assuming no and what you stated confirmed my suspicions. AKA, I will be able to take advantage of all graphics settings using my single GTX670, which should also be able to max out all borderlands 2 settings (including physx).
You don't need a dedicated physX card to take full advantage of PhysX - you just need an Nvidia GPU. Since the game isn't released, I don't know exactly what sort of performance hit the physx settings will have on a 670, but I'd be shocked if you actually needed a dedicated physx card.
