What features do you want/need because is there any reason to justify spending that much

for example why do want atx

the features i would like are good onborad audio and a nice onborad networking solutions. good power delivery for stable overclocks would be useful as well.

well from the boards you listed i would go with the Msi personaly. But  the feutures are  mostly equal to the Asrock killer. thats also a good looking board.  but don´t expect mindblowing overclocking ability from those lower budget boards..but in the basic you should be able to do a little overclock. but those boards are not realy designed for extreme overclockings.
