GTX 670 with a 9600GT as PhysX?

[Liarma]

Hey guys.

Just wanted your opinion if you think a 9600GT will be enough as a PhysX card if I'm using a GTX670? I've heard if the PhysX card is too slow it brings down the overall performance? What do you guys think?

 

[Terrifictez85]

Dedicated Physx cards tend to slow down the performance. Linus did a video on it.

i would have thought a 670 could handle physx fine to be honest mate but a 9600gt would be good enough i would think

try it without the 9600gt first to see if there is much difference

 

[Pr3d4t0r]

the crappy processing and technology of 9600gt will actually bottleneck the performance of the 670.

try a physx game with it and without, something like mirrors edge, it uses physx.

You will bottleneck the gtx 670 actually. Nvidia recommends using a card with the same first digit or one lower for a dedicated Physx card i.e gtx 670 with gtx 6xx or gtx 670 with gtx 5xx.

The 9600 is to week and will bottleneck the GPU. You have to keep in mind that a PhysX card is just like another CPU. When you pair a weak CPU with a powerful GPU you will bottleneck the GPU, the same applies with PhysX cards.

Ok guys thanks for the feedback. I thought a 9600GT doing PhysX calculations only, it would be enough but I guess not.

I used for a while a GTX 9800+ as dedicated physX card with a 680 and the performance change in games like Batman: AA, Metro 2033, Cryostasis, and Mirrors Edge was negligible. Like maybe 5 frames per second better in a few specific parts. Really not worth the extra power consumption and heat.

How about a 9600GT as a PhysX card for the 560Ti?

 

[Rastalovich]

Wouldn't bother myself.

Possibly, a 260 onward and a 560 might see some benefit. Wouldn't break my neck finding out tho unless it was spare kit laying around.

the 670 on its own should function perfectly fine, does for me on BF:BC2, BF3 and Deus-Ex
