Hi there have bought gigabyte z77x-UP7 nearly a month ago with 3770k. I have chance for selling them at a good price to one of my friends. I intend to buy the new gigabyte z87x OC Force or Asus Maximus Extreme VI with 4770 k. So first of all , would I feel any difference? Second which is better of the two 1150 boards suggested above? Any advice....also for the rams what do u suggest for me Corsair or G-skill and which category thx all
