I just purchased an Intel i5 4670K, ASUS Z87-A Motherboard and Corsair H80i Water CPU Cooler. I was debating on which motherboard to buy: ASUS Z87-A ($155) vs. ASUS TUF SABERTOOTH Z87 ($260) vs. ASUS Z87-PRO ($175). I went with the ASUS Z87-A since I was running a little short on cash. I could have still went with one of the more expensive ones but I would have pushed my budget. I am planning on overclocking the 4670K, so will there be a big difference in overclock if I were to have bought one of the more expensive MBs? Do you guys think I should return the ASUS Z87-A and get a more expensive MB?
