question Silly Question... What could happen and what I could do if I put a GTX 1070 Ti + 970 on my system.

Basically the title, this probably is just plain dumb and I think that probably it wouldn't boot.

 

Could I use the 970 for physx?

 

Or this is just doesn't have any use.

 

Thanks!

It will be useless basically.

You could have an additional three screens.

 

Using it for PhysX is kind of pointless because of how few games use it extensively enough to warrant a dedicated physics processing unit.

[Jumballi]

It will work, albeit most games want a more powerful cpu

[GrockleTD]

it'd work excellently for folding@home, but it wouldn't do a whole lot for gaming

[Mick Naughty]

Might cause the pc to blow up. Or do nothing. Who knows.

Why would you think that having 2 graphics cards would prevent booting?

 

Yes you could. You shouldn't, but you could. It will be slower than just letting the 1070 Ti do everything.

It could have use if you were doing some kind of rendering that could make use of multiple un-linked graphics cards but for general PC use or gaming it is pointless.

I'll keep it stored till I get enough money for a second build to giveaway to a cousin. 

 

Thanks for all your replies!

You could but it's not really that useful since you can't use it as a SLI setup, and even if you could, it would only operate at the performance of the 970.

 

It's the same with pairing a Radeon or using the iGPU. There are some specific OpenCL/CUDA/GPU-Compute purposes where this can be used, but it's not going to help much at all in games since the presence of the second GPU will impair the number of PCIe lanes already on the MB. So you might have 16 lanes to the 1070, but with the 970 also installed, they only get 8 each.

That depends on where the second card is installed. Also a 1070 isn’t gonna saturate 16x. Would perform the same.

You could use the 970 as a dedicated method of recording game footage (using OBS)

Not streaming, but offloading a high bitrate NVENC recording so that it doesn't interfere with your CPU/GPU gameplay.

Experts on here say that isn’t possible.

With Blender Cycles, you should be able to use both cards in a render, though the scene must fit into the VRAM of the card with the lowest capacity.

 

Basically, compute applications are the only thing remotely commonplace that would utilize the performance of such mismatching GPUs simultaneously.
