Could i run 2 GTX970's with crossfire?

Solution
The problem with Nvidia's SLI that your mobo needs to support it as it only accepts the cards to run at minimum 8x speeds while crossfire will run at any speed , even 4x that's why CFX is supported by most motherboards which have 2 PCIe slots while SLI isn't.

Nvidia does that to make sure that the user will benefit from the greater bandwidth and to ensure that they're having a greater experience without stuttering furthermore to get paid more by the motherboard manufacturers :)

With that being said if you're mobo has 2 16x PCIe slots or 2 8x PCIe slots it should support SLI however you need to check your OEM's website.

crossfire is for AMD cards. SLI is for nvidia cards. check if your motherboard supports SLI.

and it's not because the card works on your PC you can SLI.


I hvae a gtx 970 for example, but my motherboard only supports crossfire.

if you go the the website from the manufacturer of you motherboard, you will be able to look up if it supports SLI,
