Im thinking of upgrade my motherboard from Asus m5A99x to either Asus Crosshair V Formula-Z or Asus Sabertooth AMD 990FX Chipset can anyone tell me the difference in them especially in overclocking? Ill be using an fx 8350, if i wish to overclock this CPU with watercooling or Corsair H100 with each of those motherboard what is likely to be the difference? also there is about £50 difference is it worth the difference in price to get the V Formula-Z ?
