Im getting new card this/next month and I saw that 660 is good for its price. But now I want to know if I should choose MSI or Gigabyte card. Gigabyte should be better but its more expensive too. Only difference is clock speed. MSIs speed is 1006MHz and Gigabytes got 1033MHz. How much theres differend in FPS in some modern games. If its less than 5 frames Ill get MSI. I will NOT overclock any components at home. My built will be i5-3570, 8Gb 1600MHz RAM, 600W PSU (that can handle 660).
