I don't think you can possibly bottleneck your components, even if you utilize the slowest memory standard your motherboard supports, i.e., DDR3 1333.
I suggest get G Skill Intl F3 Series RAMs or Patriot Memory 2400C10 Series. Both are really fast and they're in the same league with your mobo, CPU, and GPU. Maybe DDR3 3100 overclocked? 2500 overclocked? or 3000 overclocked? So on...Your chipset supports many memory standards, so...The memory standards I mentioned are definitely optimal, but that depends on what you prefer and what your budget is. I hope my feedback helps.
