How relevant is the type of motherboard in terms of pc performance during gaming if you're not overclocking anything?

There are only two things I look at when choosing a motherboard; quality and expandability. The most important aspect of a motherboard is that it is durable, stable and reliable. The second is expandability, a motherboard with 7 full size PCIe x16 slots is much more favourable than a motherboard that has only say 3 x16 2 x4 1 x1 and 1 PCI slot.

They say the amount of lanes available for expansion is limited and there are not enough lanes to provide the full 100% bandwidth for 7 PCIe x16 slots. To that I can answer that this is a "problem" that Intel and AMD is supposed to find a solution for. Moreover, I don't believe that *all* hardware uses *all* available bandwidth at once so there should be a smart way to distribute the bandwidth over all of these slots. Then of course this bandwidth distribution may yield a small penalty in latency. But then again, the user should be able to turn this off in BIOS if the penalty is too costly for the user's application or be turned off automatically if such bandwidth management isn't needed.

At the very least, a full size x16 socket with pins for only x1 PCIe can run a full x16 card. The only thing that will happen is that the card will only have access to x1 bandwidth and thus may run slower, but apart from that it should work normally unless the limited bandwidth is a problem for the card.

An on-board Intel PROSet Ethernet controller is favourable over say a Realtek controller, and LSI based SAS/SATA controller is more favourable over say a JMicron controller which is shit, or Marvel although I don't think they are so bad, however their driver support isn't as good as LSI. For Wireless I would favour Broadcomm for now.
