Good luck with that motherboard (z97n gaming 5). I had it for a week. It's my number 1 most hated motherboard of all time. It's very buggy. Settings not saving, RAM needing excessive voltage for stability, XMP working about 10% of the time. I could go on lol..
I have used nearly every CPU from Sandy Bridge on and Phenom II on. I have also used most GPU's from 2011 on, from low, mid and high. I've built 100's of rigs over the years. Most for fun and some for side work. If you have any questions and want an unbiased opinion, please feel free to PM me.
