I have a GTX 670, would I benefit using my old 9400 as a physx card?

The question is pretty much the title, I got an old 9400 gt laying around, would I benefit using it as a physx card or would it just cause more bottlenecks?
 
I don't believe so.

I think keysplayr on these forums did some testing with and without a dedicated low-end physx card. Maybe PM him for his conclusions.
 
Depends on the game....some games will benefit like mafia 2 but others will barely show a difference with a 9600gt.

IMO there's no way its worth it. I personally would not.
 
the 9400gt is so slow that it does not even meet the requirements to be used a dedicated physx card at all. even a 9500gt would do nothing but slow you down compared to letting your gtx670 do both graphics and physx. a 9600gt might break even compared to your gtx670 doing everything so even that would be a very poor physx card.
 
A 8800GT might have helped perhaps, but a 9400 GT is probably not even half as half. 8800GT too might or might not help. So 9400 is a waste IMO most probably 🙂

an 8800gt is about 5-6 times faster than a 9400gt in games.

9400gt
16 sp
8 tmu
8 rop
12.8 GB/sec mem bandwidth

8800gt
112 sp
56 tmu
16 rop
57.6 GB/sec mem bandwidth
 
Okay, I had to check that myself. Looks like, your card (9400GT) doesn't even meet minimum system requirements to run PhysX. Wish, somebody else had already checked that.

The minimum requirement to support GPU-accelerated PhysX is a GeForce 8-series or later GPU with a minimum of 32 cores and a minimum of 256MB dedicated graphics memory. However, each PhysX application has its own GPU and memory recommendations. In general, 512MB of graphics memory is recommended unless you have a GPU that is dedicated to PhysX.
