HDD Seagate Barracuda 7200.14 3TB
MBD MSI Z170A PC MATE (MS-7971)
RAM Corsair Vengeance LPX 16GB (2 x 8GB) DDR4 DIMM C14

I was wondering if I should switch the motherboard and get DDR3 ram instead of the DDR4. I read about it (post from February 2015) saying DDR4 doesn't give as much value.
 
Solution
I'd stick with the Z170 mobo and DDR4 if going Skylake (I would however, lose the MSI mobo and maybe go with the Asus Z170-A. I won't build on MSI due to their poor QC Another option would be to go Z97 with say a 4690K and DDR3

I think Ill stick with this build, I'll just risk it with the MSI MBD. Thanks for the help.
