Dual gpus

[Bright7185]

When building a pc with dual gpus do they have to be the exact same but without sli like if you want one gpu to run to different monitors and then the main gpu to run one proper gaming display the other gpu is entirely not used in the one display. Is this possible once again not with SLI or anything like that just 2 different gpus doing seperate things?

Yes it is, I am using this at the time GTX 1660 as primary card and GT 710 as secondary gpu, you might find some driver problems thugh

Yes, that's possible, just use them without SLI bridge. It's a good idea to have both Nvidia or both AMD cards to prevent driver conflicts.

I am not sure where your introduction ends and your question begins, so please do ask if I missed anything:

 

Q: If I want to run SLI, do I need two exactly the same videocard?

A: they need to have the same chip and same amount of VRAM, but don't need to have the same cooler. E.g. Two 2070 Super videocard, one from EVGA the other from ASUS would work. A 2080 and 2070 together would not.

Q: Which card should I plug my monitor(s) in?

A: doesn't matter, plug it into either card.

 

Q: Can I run my secondary monitor(s) off my secondary card?

A: Why would you do that? Just run them from the primary card.

 

Q: In SLI, can the two GPU's do separate things?

A: SLI is there to make videocards work together. If you don't want them to work together, that's also possible. But then I would question why you want to run SLI.

 

Just think long and hard on if you need SLI. You don't need SLI for multi-monitor support, you would need it for more  performance. But then again, getting two 200 USD cards is usually worse than one 400 USD card. For example.

Especially since your motherboard and PSU need to be fit for SLI too.

Sorry for the way I put the question what I meant to say was if you dont want to run SLI but you still want 2 graphics cards do they have to be the same?

No for short answer
