If you don't plan on overclocking, the chipset dosen't really matter, as long as it fits your peripheral needs (plugs for all your components). I would consider the following brands : AsRock, Asus, Gigabyte. These are the most common motherboard brands and the best for the quality (in my opinion).
If you buy a Gigabyte board, a Gigabyte graphic card won't change anything, performance will be the same.
Between those two boards it is a question what expansion slots you want The Asus has 2 x PCIe X1 and 1 normal PCI and the Gigabyte has 2 x normal PCI and 1 PCIe X16 slot that runs on X4.
Performance will be the same and they work equally with what ever GPU you get.
