I don't know if you read where Tomshardware took a dozen motherboards to answer if the game results changed as you changed only the motherboard. They used the same memory, CPU, GPU and drives and the result was withing 1 per cent. Low enough to account for measurement error.

That means it's not a motherboard question when it comes to gaming but the GPU FIRST, then the CPU (I have a link about the i5 2500 driving 3 GPUs handy) and then the rest of the parts.

So no, I would not compare boards when it comes to gaming. There will be folk that think it matters.
