I moved this thread to the System Builders Anonymous forum.
Those do not look like very reasonable choices for motherboard and memory.
If you like MSI, what features does the $190 Z370 Gaming Pro Carbon motherboard provide that you would miss with the $143 Z370 SLI Plus
? If you like Asus, how about the $162 TUF Z370 Pro Gaming
That $550 memory kit is an overpriced extravagance. $185 G.Skill F4-3200C16D-16GVKB
or $240 Corsair CMK16GX4M2B3733C17R
or even $215 Crucial BLT2K8G4D30AETA
would provide very similar real-world performance for hundreds of dollars less. You could spend the difference on a high-performance PCIe SSD or on a 2x16 GiB kit like the $414 G.Skill F4-3200C15D-32GVK
to double the amount of memory.
