Graphics dedicated PhysX card?.

im running a 9800gtx i tried useing 8600gt for phyx but it did not cut it what card would you recomend for phyx ???...

 

Actually your card is the one recommended as PhysX accelerator .

 

the 8600gt i was useing was the 256mb version

 

You are missing the point. When we talk abou thigh physx in Batman and comparable effects, then we talk about gtx260 or higher as main card and 9800gtx as aditional physx accelerator. Anything lower and physx talk is pointless. 8600gt was enough for mirrors edge, but it's nowhere near usable even for low physx effects in batman.

 

its only worthwhile possibly for what, 3-4 games? theres not enough games that use phys-x heavily enough to warrant a dedicated card for in my opinion.

 

Of course that is another point, there is just not enough games with PhysX support at all.

 

Test show, that a card with under 64 CUDA cores, will usually have a negative effect on fps. Thus, a 9600GT or similar would be the minimum card suggested for use.

 

2 9800GTX+'s are perfectly fine for running Arkham Asylum, I'd recommend playing it in XP if you have something like a Athlon64x2 as 7 and Vista's implementation of DX9 seems to have more overheads, but with an i5, and probably a core2 duo/quad you'll have perfectly playable minimum fps for 99.99% of the game. Only certain smoke coming from 2 vents in the game will reduce it to below 25FPS.

To the same extent after measuring the 2nd 9800GTX+'s GPU usage during the most Physx intensive scenes, it only uses 50% so I'm willing to bet a 88/9800gt would do just as well.
