Motherboards mainly effect connectivity and offer varying features, performance is rarely effected between different motherboards. There big exception is on the AMD side, as their CPUs are very power hungry, and the 8 core models can run into throttling problems on the lower end motherboards, as the cheap boards have weak power delivery systems that can't handle the CPU's power draw without overheating. This isn't an issue on Intel boards, as their mainstream CPUs consume less power, than AMD's and overclocking is locked out on the really low end motherboards with the really weak power delivery. As such, if you do wind up drawing power comparable to an AMD processor, you're likely going to have the power phases to handle it as overclocking is only allowed on the more expensive boards.
