Designed for true power users, the P8P67 WS Revolution uses a built-in controller that enhances bandwidth availability between the board & the four graphics card expansion slots. This is ideal for NVIDIA Ge Force SLI & AMD Cross Fire X, as the motherboard can easily handle 2-way SLI in dual PCI Express x 16, while 3-way SLI works in dual PCI Express x 8 & one x 16 link. This translates into a 26.4% performance increase compared to regular P67 motherboards with similar SLI configurations. For Cross Fire X, the P8P67 WS Revolution supports up to quad GPUs builds in PCI Express x 8 links, unlike standard motherboards, which lack the bandwidth to do so.
