I recently purchased a asrock z-77 Asrock extreme6 from microcenter. I questioned the staff if it was an open box due to no seal, I was assured it was not. Later at home, I noticed a couple of inserts missing. Now I see that microcenter has discontinued this board. I am still within my return period and I am thinking about swapping to a gigabyte ga z77 ud5h. Which would be the better board coupled with a i7-3770k? used for light video editing and adobe cs6.. I also play with blender 3d quite a bit..I feel uncomfortable with the asrock mainly because I will not be assembling the system till august, (out of return period, and dealing with rma stuff should I encounter a problem). But mainly which is the better board?
