MSI doesn’t include an SLI bridge with its P55A Fuzion, assuming instead that Nvidia graphics users will always chose HydraLogix N-Mode over SLI, even when the cards are identical. While that’s not a problem for a site that has SLI bridges laying about the test bench, it could be a problem for some buyers. With the bridges missing from the P55A Fuzion, most buyers who insist on SLI capability would choose a different board rather than buy the connectors separately. This makes sense, since you're paying extra for the HydraLogix functionality up front. Our desire to produce the most realistic configurations led us to add a second motherboard to the test, ASRock’s P55 Extreme4.
The P55 Extreme4 is slightly better-equipped by way of USB 3.0 and SATA connectivity, but doesn’t have a PCI Express bridge on the CPU’s sixteen PCIe 2.0 lanes. Like most P55 motherboards, it switches from x16 mode to dual x8 mode when two graphics cards are installed. We used it for single card, SLI, and CrossFire tests.
