I recently bought 4 computer parts for 40 dollars (i7 860 w/ stock cooler, asus sabertooth 55i, amd hd 7770, and a single 8 gb stick of pny x
r8 ram) and i was wondering if it is necasaary for me to get a second 8gb stick or if i could stick with a single stick. I dont plan on doing anything special with it, (light 2d gaming, youtube, twitter). This annoying kid i go to school woth keeps talking down to me saying i will need 2 sticks, but i dont believe i would need 2 for light gaming.
