GTX 650 DEDICATED PHYSX CARD FOR GTX 770?

Sorry the thread title is screwed up

I have a GTX 770 which I just got on the cheap. My old GTX 650 is laying around. Will my games improve or be worse off with 650 as a dedicated physx card??

I tried running a GTX580 as the Physx card for my SLI x2 GTX780's.... and got no improvement at all, even when specifying the 580 as the PhysX card. It even slowed things down in some benchmarks.

I did some research at the time... and most of it deemed it useless...

Is it at least worth it for games that are heavy in Physx?

I didn't see any improvement at all. I will try to find the links to this that I found when I was researching it.

My suggestion... try it.... test it.... that is the only way you will know for sure.

A couple of links...

agreed. I've seem very little improvements when trying dedicated physx cards with my 780s however bare in mind that most benchmarks don't actually make use of physx because it would skew all results in favour of nvidia (or so I believe).

Try it in some physx games.... Borderlands 1/2, Batmans etc and see

I tested with Futuremark 3dmark and Crysis 3 benches, both of which are physx capable. As you stated... very little to no improvement.

I tried both a GTX260, and a GTX 580 as a dedicated cards... with a pair of 780's in SLI... no dice! Disappointing! biggrin.gif

I also tried a GTX780ti with 2x 780 ti's in SLI and made no difference either.

The latest 3D Mark isn't physx enabled though (firestrike etc), I think 3D mark Vantage was the last one that could make use of it (maybe 3D mark 11 too, can't remember)
