Z77 asrock or asus sabertooth

i'im about to build a 2nd gaming computer. my 1st build had the asrock z77extreme4. to me it was great but i didn't oc or do anything other than surf web and watch movies. i got it for 90 with purchase of i5 processor so the price was great. now I'm deciding if i should go with asus sabertooth for 189. is the price worth it. now this build is going to be for me,and i don't want to worry about upgrading for years. also i got the nocuta heatsink 92b. and the corsair vengeance was blocking the fan. they have huge heat spreader. i want to get a 2x4gb ram 1600 that has potential to OC without the huge heat spreader. any recommendations?
