I've been reading into old tomshardware motherboard reviews on the ivy bridge architecture, and I've been wondering what they mean by how some boards benefit by having a PCIe switch and others don't. Of course the most important part, what is the application or instant benefit as a user.

it is a device that allows more than one pcie bus to run at the same time.

Yeah I kind of figured that. What I'm asking is, what are the benefits/consequences of having the switch on vs. off.

if you do not have a switch, you could not use all of your pcie slots at the same time at full speed.
