Gigabyte Z87X-OC Force Motherboard
 

Head on over to Hardware.Info today to read their review of the Gigabyte Z87X-OC Force motherboard. The main difference is that the Z87X-OC Force is equipped with a PLX PEX8747 chip that can double the 16 PCI-Express 3.0 lanes from the CPU. Because of that, the four orange PCI-Express slots can be configured 16/0/16/0, 16/0/8/8 and 8/8/8/8 which supports 4-way SLI and 4-way Crossfire. The black PCI-Express x16 slot is directly connected to the CPU, so if you have one video card you want to overclock you have 0 extra latency. It's a clever solution we've seen before with MSI and ASRock.
