GTX 690 with GTX 560 ti as dedicated physx card

xxThe_Dice_manxx · Jul 23, 2014

I use a GTX 690 but I also have 2 old GTX 560 TI's sitting around doing nothing.

Is it viable to use one of the 560's as a dedicated physx card?

Or can anyone recommend another way to put these 2 560's to use?

I can't be bothered selling them as they are in mint condition and I won't get anything near what I paid for them.

I haven't got the cash to build another PC using them in the build.

That dual GPU GTX 690 won't even know it is doing the PhysX computations. PhysX is not very demanding. That's why the CPU can do it on non-PhysX machines w/o much added effort.
If you still want to use one of them just because you have them, go ahead. More heat and another heavy load on the PSU. But if they were mine, I'd sell them in a heartbeat. And no, you never get what you paid for them when they are 2 generations old. But you will get enough to use the cash for something else.

It should be comparable to a GTX 650 as a dedicated PhysX card. Maybe even better, since it has "hot clocked" CUDA cores (2x the core clock speed).

I would imagine having a dedicated physx card will help a lot with Metro:Last Light because I get constant 15-20 FPS drops with physx enabled in that game with my current system. Gonna pick up a 750ti tonight when I get paid for a dedicated physx card.

zaysk :

Here's a great review with the GTX 750 Ti as a dedicated PhysX card.

Thanks for the reply, and thanks to all who replied, will probably use one as a dedicated physx card now, as I have a 1000watt PSU and no heat problems.
