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.
