The reasons that CPUs bottleneck GPUs are for 2 reasons.

1. The CPU is working too hard to send the information to the GPU(s). Which would only happen if you are running a CPU that is below the required specs for the game.

2. You are using too many PCIe lanes for the CPU. Your CPU has 16 PCIe lanes, but those GPUs only really need somewhere between 4-6 per. So that CPU is fine for 2 of them but 3 might push it a bit and 4 I wouldn't recommend for a multitude of reasons including the lack of PCIe lanes.

Should be fine, you'll start getting bottle necked around 3 GPUs by the PCIe controller on the CPU,

And 4 way SLI is just crazy on this chipset.
