2 gtx gpu.

Hi experts.
Is there any advantages or will it work, adding my old 1070ti to my machine with a 2080ti.
I already have 4 screens attached to 2080 so would the 1070 benefit me or just a waste of power and time??

waste for sure

Personally id sell the 1070Ti and 2080Ti and combine the money and possible add a few to buy a newer more powerful card if your looking for more performance,Both the cards you have still fetch a decent amount especially the 2080Ti.

What do you mean by "will it work"? You can only have a single GPU configured for display so the 2nd GPU would have to be used for other purposes. You can't include SLI as a purpose because they are not the same architecture.

Nvidia drivers often have issues with multiple gpus in a system with a different architecture. This has happened in the professional space where they had Maximus which was Quadro and Tesla but they had to be the same generation otherwise it would cause a multitude of issues. We have had customers wanting to put old geforce in their system with a quadro for a bit of extra compute power but it rarely will work and often crash during startup or image deployment due to it getting conflicted which gpu to use as primary.

Sell it and stick some more memory/nice fast ssd in your system along with the 2080ti.

Depends on what you're using the pc for....

A second card could be used for cuda/physx calculations which would likely be faster than using a cpu for the same task, but you also run the risk of conflicts due to differing architectures.

If only explicit Mgpu took off...

Has this changed then? I used to run multiple displays off multiple GPUs.

Not to my knowledge (I actually missed that bit in that post).... I know I could run my old 4790k with the igpu and my nvidia together without any issues on windows 10, I doubt things have changed much.

Yeah I'd be surprised if it doesn't still work. I believe there's some quirks like sometimes the actual graphics processing might not happen on the gpu that the monitor is connected to, but from a functional perspective, you should be able to display windows on monitors not all connected to the same GPU.
