Why do most (if not all) Micro ATX motherboards sacrifice a PCI Express slot in a dual SLI/xFire setup?
Hi I'm new to these forums and any help you could offer would be much appreciated
I'm looking to build a Micro ATX gaming rig with dual SLI/xFire setup, in a case that has five expansion slots. I also have a x1 PCI-e TV Tuner which I was looking to install alongside. I have noticed however that most Micro ATX mobos I have looked at such as the ASUS Maximus VI Gene, have a PCI-e x4 slot that would be inaccessible in a multiple GPU setup.
My question, is there a reason why gaming/micro atx motherboards favour the first PCI-e slot to be x16 (distance from graphics cards to CPU maybe) and not any other way? My setup would work with the above mentioned motherboard if the PCI-e x4 was first, followed by dual x16 slots.
