P67, X58, And NF200: The Best Platform For CrossFire And SLI

SLI Platform Performance: Crysis

Crysis is a fun benchmark because it’s so frequently bottlenecked by so many different parts of a system. The Core i7-2600K takes the high mark at our lowest test setting, while the addition of 4x AA is required to make the three-way SLI configuration stand out. Bottlenecked by its CPU, even the addition of AA isn’t enough to give the three-way SLI an advantage over two-way SLI on the X58 platform, yet.

Increasing our Crysis test resolution to 1920x1080 gives us much more to discuss. First of all, we notice the P67 motherboards leading at all three resolutions. But the NF200’s only advantage is that it enables three-way SLI with that same CPU. The third cards hurts X58-based system performance at 1920x1080 without AA, likely due to the extra system overhead of a third card, while the addition of AA puts it ahead by pulling down its two-way configuration.

The Core i7-2600K continues its lead at 2560x1600, its P67 platform needing the NF200 to even enable three-way SLI. Remember that both CPUs are clocked to 4 GHz for all tests, so CPU performance difference are purely related to architecture.
