Samsung 940BF vs Samsung 940BX

I'm not a gamer but I can't imagine there being much of a difference between 2 ms and 5 ms. Many reviews of the 940BF complain of the RTA not working properly and actually creating ghosting. The 940BX is a slightly newer model which has 1000:1 contrast vs the 700:1 of the 940BF. The new 940BX also has the superior base which has a height adjustment as well as a 90 degree rotation option. I'm getting the BX I just which they had a silver version.
