Can gpu be mixed?

[murph0981]

So my friend has a 1050ti and he wants to buy a 1080ti and have both gpu connected. To me it sounds odd because one would overpower the other, or is that even a thing?

You cannot combine the graphical power of a 1050 ti and a 1080 ti, and there's also no reason to do something like power a secondary display with the weaker card.

You can, but there won't be any benefits.

DX12 did invent a specification that would allow multiple GPU's of disproportionate power to be aggregated together - but to my knowledge, no GPU manufacturer has made this successfully work, nor has any game implemented this.

 

You can certainly install 2 GPU's in a system, but to combine them, you'd need to use SLI or Crossfire - and both of those solutions require matching (or nearly matching) GPU's.

Couldn't you theoretically use 1 GPU to play or render things and the second GPU to record with OBS or similar? 

 

I think that should work but not sure how efficient it is... 

 

I was actually thinking of doing that.  Or build a "streaming / recording PC" but I'd obviously prefer using a second GPU as that would be much cheaper.

 

 

PS: I looked at some "capture devices" and they're all just wtf to me,  expensive,  low resolutions,  input lag 

... I don't want any of that

Yep - though I don't know if windows scheduling works well that way. 

 

You could also game on one and say, drive displays on another.
