Can motherboards both support Nvidia and AMD GPU's?

[Iver Hicarte]

I know that you can't use AMD and Nvidia cards on the same build. But I saw some motherboards that can support CrossfireX without mentioning anything about SLI support, does this mean that I can't use an Nvidia GPU on that specific board? Because they didn't mention anything about SLI support. PLEASE ANSWER ASAP!

THANKS IN ADVANCE!!!

it simply means that you can't use 2 nvidia cards, 1 card of any type is always supported.

specific Xfire mobo?? can you link to it? when dual graphics came out , ya, they made specific mobos but technology has better since then. early mobos with pci-e after AGP went away were terrible then.

https://uk.pcpartpicker.com/product/fjZ2FT/asus-motherboard-h110md no cross fire, no SLI

https://uk.pcpartpicker.com/product/LsX2FT/asus-motherboard-z170pro Cross fire and SLI

All of these will take 1 AMD or 1 NVidia card.

wow, news to me.

Any board that supports SLI should support crossfire, but not necessarily vice versa. SLI requires at least a PCIe x8 connection to each GPU, while I believe crossfire only requires x4. This means that for Intel mobos, only Z series boards ever support SLI (but not all Z series boards do).

is this a money saving problem for the board manufacterer? are the boards cheaper? seems to me the x-16 x-8 x-4connectivity would be backwards compatible by now.

It's more a decision by Intel. They only allow the 16 PCIe lanes from the CPU to be split between multiple slots on Z series motherboards. And PCIe lanes from the chipset can only be up to x4 for a single connection. So there's no way to get at least two x8 connections on a non Z series mobo.
