GTX 760 SC 4gb w/ 750 2gb dedicated physx

[Digicats]

Hi all! This is a first post i've done here but i use the site all the time for various computing questions. I recently bought a new computer from ibuypower and it's coming with a gtx 750 2gb as part of a free upgrade deal they're doing. I currently have a EVGA GTX 760 SC 4gb and i'm just wondering if i should pull the 750 out when it arrives and put in the 760 or leave the 750 in as dedicated physx and put the 760 in as well?

If you want to run the two GTX cards in SLI, first make sure the motherboard supports it.
If it doesn't, you can only have one card installed.

If you have to use one card, my choice would be the one with the most VRAM (the 760 SC).
You don't have to choose between having the PhysX engine or not having it since both cards have it.
Therefore the choice is a no-brainer.

If motherboard supports SLI and you decide to install both, don't forget to make sure your PSU is powerful enough to run both together.

SLI and dedicated physx aren't the same thing i thought. Regardless, the mobo supports it.

It will work, you could even run a dedicated physX card off a 4x slot, and it still would work. You just install both cards hook up the monitor to the 760 and go into the nvidia control panel and enable it. Normally depending on the game you will see a performance increase, but not for all. The only thing that you need to make sure of is that you have the 760 installed in the 16x slot which is normally the top. But since your board is a x79 board you won't have any problems with that at all.
