The only absolute requirement for a gaming motherboard is a pcie X16 graphics card slot.
Every modern motherboard will have that.
I might suggest that your choice of cpu is weak for a GTX780 class card. A intel quad would be more appropriate.
That will be in the $200 range.
Today, I would look at one of the Z97 motherboards if you will use a overclockable "K" cpu, or a H97 motherboard of you will not have a "K" cpu.
