Hi mates, Please help me with two questions I wasn't able to answer after *a lot* of googling. 1. The vast majority of h370 and b360 boards with two mechanical 16X slots do have the following layout: the upper slot has 16 gen3 lanes by the CPU. The lower one has 4 gen4 lanes by the PCH. Now, I need to install two video card.One in the 4X slot for driving the monitor and gaming, and one in the 16X for computational purposes. The two cards won't be connected by a sli bridge, obviously. My question: is it doable? Will the 4X (PCH) slot provide video output? 2. The z370 and the b360 seem to provide identical features: which are the differences?? Thanks!
