I just finished upgrading my Hadron from an AMD A8-6500 on a Gigabyte F2A88X motherboard. I decided to go Intel this time. So far it has impressed me. Although the processor speed is lower, the system just runs so much better now.
I decided to build the upgrade around the i5-4690k processor run the OS from an SSD drive. Wow, it boots before my monitors are ready. The only issue I ran into was that I couldn't use my GSkill Ripjaws PC1600 memory due to the height limit under the SlimHero HSF. I had to put in an older Team Elite Plus PC1333 memory.
I have to make some mods to clean up the cables, and mount the SSD, but it's up and running.
