Which of these rams should i get for gaming?
Patriot Viper PV38G186C9K 8G Kit(4Gx2) DDR3 1866
G.Skill Ares 8GB Kit (4Gx2) DDR3 1600 F3-1600C9D-8GAO
Kingston HyperX 8G Kit(4Gx2) DDR3 1600
Go with Patriot Viper as it has a memory clock speed of 1866MHz which is slightly faster than 1600MHz. Some may argue sayin that you will not notice any difference, yes, you will not see any major difference but the system will experience it.
1600MHz (Kingston and GSkill) memory is considered as the entry level speeds for the current motherboards (Z77). I'd suggest to go with the Patriot memory else you may go with any brand you prefer. If you need some other brand with 1866MHz then search for it or give me a shout, I'll do it for ya. Good luck mate!!
