Benjamin recommended me to go with AMD instead of Intel. So I will be getting the AMD Ryzen R-3700X.
For RAM, Benjamin recommended the G.Skill Trident Z Neo Series 32GB. It is a PC4-28800, 3,600 MHz, 288 pins RAM with a CAS Latency of CL16 (16-19-19-39) at 1.35V.
AMD Ryzen works better with faster RAM followed by lower latency, so I chose that instead of 3,200 MHz with CL14.
It retails for US$184.99 (S$257) on Amazon and shipping to Singapore is an additional US$5.39 (S$8).
