I'm looking for a Motherboard that gives me a good gaming performance and comes for a great price. MSI has me hooked on the MSI Z170 Gaming Pro Carbon but it has 3 PCI-E slots. 2 of which are Steel Series and make use of 16x, the third is and 8x. I am using a Plextor M6e Black edition 256gb SSD and a EVGA GeForce GTX 1060 SC. Therefore i have the 8x left. Is this worth it and what could i do with this last slot as i would like to make the most out of my motherboard?
