thanks for the input.
on the PSU, I will change it to a better quality.
on the CPU, will there be any difference if I stay with the i5-8400 and the Z370 mobo?
Apologies, I forgot my budget.
Budget: 1500 USD
Country: Thailand
for the GPU, i'm mostly playing RPGs (skyrim, Mass Effect, WoW) and I'm planning to use VR on that machine.
