LHFIVE :
Is it worth the extra, to just get the ASrock extreme6. Also, what do you think of the ASRock Z97 Anniversary
Yes it is. Plus, you've got a GTX 980 Ti and a i7 4790K. Those two products are the most expensive items in their categories. So for me, cheaping out on a mobo doens't make sence. (However, I'm not trying to bash you or do anything like that. I just find it funny that you would buy a cheap mobo with an EXTREMELY expensive CPU and graphics card.)
I suggest staying away from the anniversary edition mobos. Basically, what the anniversary edition mobos are is h81/b85 mobos with the z97 chipset slaped onto it. So you get basically none of the advantages of Z97, except for overclocking.
Again, I just want to say that there is NOTHING wrong with pairing a cheap motherboard with an expensive CPU and GPU. I just find it funny that you would spend so much on one thing and not the other.
