Dual Graphics Card - GTX 750ti + GTX 1060 6GB OC

Chris_1776 · Mar 19, 2017

Hello,

I would like to ask for more information in regards to having dual graphics cards. Currently I have a GTX 750ti and have bought a GTX 1060 6GB OC Gigabyte card. I'm quite competent when it comes to building computers however this area is new to me as this is the first time that I'm to go for dual GPU. My motherboard has two PCI slots and has SLI/Crossfire.

So what I would like to know is how should I plug them in? replace the 750ti with the 1060 one and put the 750 in second slot or does it not make a difference?

Should I check my PSU and see if it can supply that much power to both GPU's?

Once they are both plugged in, what then? is there something to configure?

If there are any good youtube video's out there in regards to this please let me know

Many thanks,
Chris

You can't SLI unless they are identical chips for example (GTX 970 + 970 but NOT GTX 980 + 970 or NOT GTX 950 + 1050). Best thing to do would be sell the 750 Ti or gift it to someone haha. Hope this helps

And 1060 does not support SLI

First, the GTX 1060 and the GTX 750 Ti do not support SLI.
Second, You can only do SLI between two identical chips as explained by CRO5513Y.
If you were going steady with one 750 Ti before, I'm sure you will be pleased by one 1060 as it performs way better than the 750 Ti lol good luck!

Sidenote, SLI is only support for cards higher tier than the 970. I.e. 970, 980, 980 Ti, 1070, 1080, 1080 Ti, Titan
Crossfire is an option as well for radeon. Plus SLI/Crossfire usual comes with unwanted problems so it's porbably just better to stick with one card! Hope this helps

As the others have said, you can't SLI the 1060 and 750 Ti together. You can, however, set the 750 Ti as a dedicated Physx card. Physx is a proprietary Nvidia physics technology that can have a pretty significant impact on your FPS. If you set the 750 Ti as a dedicated Physx card it will handle the Physx duties and take some of the strain off your 1060 so it is free to do everything else.

One thing to keep in mind is that there aren't that many games that use Nvidia Physx these days. Most games will simply ignore the dedicated Physx 750 Ti and do everything on the 1060.

If you are just going to have it sitting around anyways you might as well use it as a dedicated Physx card but it might be worth looking into how much you can sell it for since most games won't use it.

you can sli a gtx 960 and a gtx 1080 but the gtx 1080 would only use a tiny portion of its power (it would make it reduce its power to the power of the other graphics card) and not many gtx 750 ti supports SLI and the only cards (in 1000 series) that support SLI is GTX 1070, GTX 1080 and the newly released GTX 1080 TI but its not available with aftermarket coolers and that means the GTX 1080 TI has absolute SHIT cooling and temeratures

GDAlpha :

No, you cannot SLI a GTX 960 with a 1080. It must be the exact same graphics processor as has already been stated unless you are referring to dedicated PhysX cards, then it is possible.

The only other way to use both cards at once, outside of dedicating one to PhysX usages would require Vulkan or DirectX12 in multi-GPU mode. However, I think there may be a performance penalty depending on how it's set up. Yet.. from what I understand DX12 isn't near ready for this, and Vulkan is on the verge of release.

Personally, I'd just use the 1060 (non-crippled version) you got as the primary GPU... I'm not sure that the 750ti would provide enough cores to be effective enough for it, but it might be enough for PhysX, which is where I'd dedicate its use to if I left it in the system.

it will work but most of the time one of the GPUs will disable/idle

You can use both the cards in Explicit Multiadapter mode through dx12 but currently Ashes of the Singularity is the only game supports it .Lets hope it will be implemented in more future games that are adapting SFR
