I believe jacksfrag on youtube built a nice gaming pc for about your asked $400 range.
Your motherboard has to have the same chipset as your cpu.Like for example, a i7-3770k has a z77 chipset, therefore the mother board has to support z77.Chipsets are the little pins of your cpu, its like a poweroutlet, a 3 pin wouldnt go in a 2 holed outlet.Your graphic card mainly determines your outcome, though a bad cpu could "bottleneck" or hold it back from the graphic card's full power.

Check if two motherboards have the same chipset, if they do and are different prices.One probably has more slots etc.
