Never mind, when I updated Community tech tree the location of certain parts changed and I didn't have the techs unlocked yet.

when I launched ksp after 6 months, the 5m parts had Z fighting so I went through your troubleshooting check list, I was halfway through the list when I managed to delete the entire Game Data file, after reinstalling the Game Data folder and my mods(DMagicOrbital Science, KJR, MechJeb, MRS, LET Space Y, Space Y Expanded, TweackScale, Community Tech Tree, and Interstellar Fuel Switch). KSP won't load the Heavy lifter parts pack, but loads the Expanded parts. I have tried a clean install of both mods.

Part of the advantages of the new Skylake processors and Z170 chip-set motherboards all have 20 lane PCie support native.

Having an a 6600k I would go with one because until you really push it the voltage draw and heat load are both low. My chip runs 4.6Ghz @ 1.37v, 4.5Ghz @ 1.31v, and every 0.1Ghz lower drops another 0.03 volts. on my old cheap cooler (a $20 Arctic freeze) would keep it at 62-66C during the summer while running 4.3Ghz @ 1.25v and was fairly quite. the only thing to note is that the 6600k and 6700k do not come with a stock cooler.
