Question What would be a good video card for PhysX support

I am wondering what people are using for dedicated PhysX support. I know you need an nVidia card for this, but how good a card do you need? Would an nVidia GTX 460 be appropriate? I would be using it in combination with EVGA GTX 580 SC video cards on a dual monitor 3D ready system with the lesser card being assigned to PhysX only support.

Don't think you owuld need such powerful card just for physx. I would just get a gtx280 which can be had for $100 used.

from what i gathered the 580 will be fine on its own, sticking physx on the 460 might make it slower, might. that's on a single screen. on dual screens the 460 could make a difference, how much i cant tell you right now.

Well I did test on different cards for Batman AA and I would say the minimum you would need is a 9800 GTX. So the GTX 460 will be plenty for a dedicated physx card.

Don't listen to dangtx because thats not true. A dedicated physx card even the lowly 9800 GTX will give significant performance boost in all physx heavy games. Adding a powerful enough dedicated physx card will NEVER lower performance on games. It might for certain crappy benchmarks like Futuremark.

well, if you put a lowly card just for physx and leave the rest to a power dog like the 580 might seem natural, but going by a test linked on another thread that's not exactly the case. the 460 is much better than the 9800 at it,just do it and let us know too

Go with the gtx 460, especially if you are sli-ing the 580's. Performance does increase as phyx cards gett better
