I currently have a Gigabyte GTX 760 OC 2Gig card. I have ordered a EVGA GTX 780 ti.

With these two cards.. can I have them both in the same system and use one for Physics? I know that I cannot SLI them, I just want to see if I can use both or if I should just sell the 760.

System specs below:

Win7 64bit HP- SP1 / i7 970 @ 3.2ghz 6-core/Gigabyte GA-X58A-UD5 Rev2 / GeForce GTX 760 OC 2 gig-Latest Driver core clock @ 1003mhz / CORSAIR H2O 620 CPU Watercooler /Corsair 1000w PS/ 12gig corsair Vengeance / Kingston 256gig SSD / 500gig WD caviar black / 2 TB Caviar /Samsung SyncMaster SA950 1920 x 1080-@ 120hz- 27"/ Logitech G-27/Fanatec Elite Pro Pedals/ButtKicker2/ OCULUS RIFT DK-1 & 2

you can use the 760 as a PhysX card. In the NVidia control panel in the configure SLI, Surround, PhysX. On the right side of the window under PhysX settings just set it to the 760.

""However, from what I've heard having a discrete PhysX can actually DROP FPS in some games. ""

Now that is not a good thing...I wont like that at all...:-(

I will give it a try and see what happens..

Thanks for the quick feed back... The community here is awesome..

Cheers

in the case that it actually does just go back in and set the PhysX setting back to auto and the computer will pick the best solution.


My computer off loads the PhysX to a 560 ti from a 2500k when set to auto so im sure his will do the same with a 760 and a 970 cpu

Your welcome. :)

I've only heard that the a discrete PhysX card can drop fps so I'm not completely sure if that's true. I hope not. :)

A dedicated PhysX card will not lower FPS in games. If the game doesn't support PhysX, it will ignore the second card. If it does support PhysX, then it will load the second card. You want to make sure that your PCI-E slots are full x16 speed. If one is a x16 and one is x16(x8) then it will drop both lanes to x8.

Whether or not that will really affect your performance is debatable. There have been numerous tests and benchmarks, and a dedicated PhysX card was almost always a boost in FPS. Even when two Titans are SLI'd with a 650 ti as a PhysX card.
