Sapphire Pure Platinum Z77 Motherboard Final Iteration Pictured

Sapphire is ready with a high-end socket LGA1155 motherboard based on Intel Z77 chipset, the Pure Platinum Z77. This is Sapphire's second Z77 motherboard disclosed so far, after the Pure Black Z77 it showed us, at CES. Sapphire is offering 3-way multi-GPU support in a very unique way. Three of its four PCI-Express x16 (long) slots are wired to the CPU, all three of them PCI-Express Gen 3.0. The topmost slot is x16 and x8 capable (x8, if any of the other two slots are populated); the middle slot is x8 and x4 capable (x4, if the bottommost blue slot is populated); while the bottommost slot is x4 capable. PCI-Express 3.0 x4 offers bandwidth comparable to PCI-Express 2.0 x8 (or PCI-Express 1.1 x16), which doesn't heavily bottleneck today's graphics cards. An ingenious slot layout, made possible by inexpensive PCIe lane switches, instead of expensive bridges.
