Hello guys. As it says in the title, i got 2 Graphic Cards. An NVIDIA GTX 750TI *that i'm using right now* and an older GT630 2GB *it's not in my PC right now*. Is it possible to use them both at the same time?

If it helps you with anything:

I3-4170 3.70GHz
8GB DDR3

Yes you can use them at the same time, for different displays but PLEASE DO NOT ATTEMPT USING SLI. It will not work and it can probably ruin something. But as I said, you can use them for different displays. Just make sure you are gaming on the one with the 750 Ti if you want the best experience.

Hope this helps,

I've seen people doing this trough SLI. I'm trying to get better performance in games. What i'm trying to say is that i want to use BOTH Graphic Cards running on one display, working together or somenthing, so i can get better performance. Is it possible?

No, because with SLI you need the exact same model of GPU. For example, if you have a 2GB GTX 750 Ti made by MSI, and another 2GB GTX 750 Ti made by EVGA you can use them, they just have to be the exact same model and VRAM. Memory and core clocks you should tweak through something like MSI Afterburner or the EVGA software....

But really it's better overall to have 2 of the exact same card models and manufacturers to have better results and overall aesthetics.

Hope this helps,

I saw a guy combining a GTX 1070 and 980Ti. One of them rendering half of the screen, the other one rendering the other half. Isn't that possible with my cards?

Anyways, thanks for your reply.

I actually don't know how that guy did it, but I would like if you could send the video or the information to that.

And you're welcome for the responses.

Yeah I was gonna say you'd need both the same card, unless he'd seen someone who had done something insane to his PC and GPUs to make it happen.

DirectX 12 allows a new form of multi GPU (not vendor specific like crossfire or SLI), that allow you to combine different GPUs. It needs to be developer implemented on a game by game (or maybe just engine by engine) basis. As said above, the only game that I'm aware of that supports this is Ashes of the Singularity.

Other than that, the only way to combine two different Nvidia GPUs is using the more powerful one as a graphcis card, and the second as a dedicated PhysX card. Not sure what sort of benefit you get, and not many games use GPU-PhysX anyway.

@danielzxe no you can't combine the performance of both those cards for gaming. Even if you could, the GT 630 is probably too weak to make much of a difference anyway.

And this is more proof that you can't trust everything you see on youtube. There are many claims there, not all of them are true. Other monitors, or as a PhysX card. Other monitors won't really make a difference, and most games aren't PhysX GPU accelerated. Meaning most of the time that 630 will be costing you money due to being powered up and drawing electricity, but giving you nothing in return. If you want a GPU upgrade you need to buy a new GPU.

(impossible as pointed out below disregard --- sell the older card and find a cheap 750ti to bridge with your existing 750ti. That'd get you something. )

Selling both and getting a single newer card would probably gain you the most improvement. But you'd be without a GPU between selling both and getting the new GPU.

Without selling anything converting the 600 series card to a physX card gets you the most benefit. Which as TJ says is questionable due to how many games actually use physX. I think it does actually yield a noticeable benefit in Skyrim. I think I saw a video where they were dropping cheese wheels down a hill and seeing how many they could spawn before the game crashed. There was a substantial increase with a physX card. I think their final cheese wheel tally was 3000...don't quote me.

(edited for lack of research as pointed out below)
