Guys I'm on a tight budget right now and I'm really confused as to which one I should get mainly because if I get the X then I might not be able to get a better cooler and a better PSU but if I get the 1600 then I will be able to keep my current cooler and also get a better Corsair TXM SERIES 80 PLUS GOLD rated PSU. Which one should I go for? Also I can only afford 2666MHz RAM.
