Multiple Graphics Cards

[Paul123]

Can I have more than 1 graphics card on my pc?

 

If yes do I need to have the same graphics card or can they be different?

You also need a power supply that is powerfull enough for two cards and a motherboard that can support more than one card.

 

Just keep in mind that SLI doesn't scale perfectly, so don't expect double the performance. Also, fewer and fewer games support it.

yes, it depends from what you want to do...

for multi gpu (two graphics cards working together in rendering a game) you have two options SLI (for nVidia) and Crossfire (for AMD and old ass ATI cards)

All AMD cards support Crossfire (except for the 5700 and 5700 XT), without any need for a bridge, only older cards need a bridge.

For nVidia (and yes I will keep the older spelling) you need to have at least an RTX 2070 SUPER or a GTX 1070) and you will need an SLI bridge.

You will need the same card for nVIdia, for AMD the cards have to be from the same generation, but still can have a diffferent GPU, nVidia is stricter than AMD in compatibility, SLI motherboards are much pricier, just FYI.

Games don't scale perfectly, and some don't even support multi gpu rendering.

In case you wanted to do some different things (a card for gaming and the other for stram encoding or PyhsX) you can have two different cards (I have a GTX 1660 and a GT 710 in the same system)

Thank you guys

hi hi hi!

 

soo you can have 1 or 2 GPUS in your PC, or technically 3 i think if you have a integrated, but that one doesnt count. 

 

so you can have up to 2. but if you want two, they have to be the same card. Im not sure if the exact same model or just the same card (EG if a ZOTAC 2080 Ti will pair with a EVGA 2080Ti, or if they both have to be EVGA cards)(BTW, even if theyre all in the same gen, still wont work, you cant have say a 2080super and 2080Ti together, must be the same type.)

 

hope that answers your question!

Sure thing. You can have as a many as the system can support. 
 

2,3 even 4. If the cpu has the lanes, mobo has the correct layout and psu handles the load.

wait wait. you can have more than 2? isnt it the max? i mean for SLI and CrossFire definitely, but like what do you even do with 4 GPUS? and what MOBOs even have that much space?

Well op never mentioned use so I’m not gonna say what max is. You can get 12 on most windows based os’s normally. 
You can do what ever you want with them. And plenty of boards take for cards. Been done for over a decade. Nothing new if you look for the right stuff and not lower end.
