I currently have a intel i5 4440 and asus b85m-g motherboard. but have decided that in the coming months i will change to a I5 4670k, and obviously a z87 motherboard. The cheapeast i could find was the Asus Z87M-Plus and i have deciede thats the one ill will most likely get. others i would consider are the ASRock Z87 Pro4, ASRock Z87 Pro4, Asus Z87-C, ASRock Z87M Extreme4. are any of these worth the extra dollars? its only about $30 max but will i get better overclocking performance out of any of the others, are are ATX motherboards just better?
