Can I use all the pci express slots on a motherboard for video cards?

post #1 of 2
Thread Starter 
I am building a rig for computing purposes. I want to get a motherboard with a ton of pci express slots and use riser cables to connect all of the slots to video cards. I am not putting the cards in crossfire/ sli or anything like that. They each compute on their own but I just wasn't sure if a motherboard would recognize all of them? It would save me from having to buy bigger ethernet and kvm switches. Also I won't have to buy a bunch of parts for multiple rigs.

It should work. A PCI-e deice is a PCI-e device, and video cards are no different.

The biggest problem you should have is if the cards are miss-matched, the drivers might not work right. Otherwise, it's a question of if the slots in question can provide enough bandwidth.
