Hi sxinyinglim,
Intel will be launching Coffee Lake CPUs on the 21st Aug (3 days away), so it might be better to wait and compare with AMD Ryzen CPUs.
But if you need to buy your PC now, then you should opt for a Ryzen build. Your games are not very graphically intensive, thus you don't have to spend $1500. Both options that I suggested below will run your games comfortably, with Option 2 (Ryzen 5 1600 & GTX 1060) being more future proof. Shop names are in brackets.
Option 1:
CPU & MB Bundle: Ryzen 3 1200 & Asrock AB350M Pro 4 @ $297 (PC Themes)
GPU:
Asus GTX 1050 2GB GDDR5 @ $163.32 (Qoo10) (After applying Cart & Shop Coupon) *
Option 2:
CPU & MB Bundle: Ryzen 5 1600 & Asrock AB350M Pro 4 @ $452 (Dynacore)
GPU:
Galax GTX 1060 EX OC White 6GB GDDR5 @ $419 (Lazada)
RAM: G.Skill 2400Mhz 8GB @ $90 (PC Themes)
SSD:
Samsung 850 Evo 250GB @ $149 (Lazada)
Hard Disk: Toshiba 1TB 7200RPM @ $63 (PC Themes)
Casing:
Tecware F3 @ $45 (Lazada)
Power Supply:
Superflower Leadex Silver 90+ Full Modular 650W @ $128 (Lazada)
OS: Windows 10 @ ~$12 (Carousell)
Total Cost (Option 1) = $947.32
Total Cost (Option 2) = $1358
