What about these:

CPU: INTEL CORE I3 8100 RM 454.00
MOBO: ASUS PRIME B360M-K RM 313.00
RAM: G.SKILL AEGIS SERIES 8GB DDR4 2666MHZ RM 349.00
GPU: ZOTAC GTX 1050 TI OC 4GB GDDR5 RM 745.00
SSD: WD 120GB GREEN PC 2.5' RM 139.00
HDD: SEAGATE 3.5' BARRACUDA 1TB RM 185.00
PSU: CORSAIR 450W VS SERIES RM 159.00
CASE: TECWARE NEXUS M RM 139.00
MONITOR: VIEWSONIC 24' VA2419-SH FULL HD IPS RM 462.00

TOTAL: RM2,945 (E Tech PC prices)

Ryzen is very value for the money for its extra cores/threads. A better PSU is always better for any build unless for office use so you its up to you if you can fork out more money for a better PSU. If you don't plan to OC, A320M mobo will suffice. If you plan to OC a lil, you'll have to go for B350 mobos which I don't think 3K budget is enough.

i3 8100 has same cores with previous i5, not the current i5. Current i5 has 6 cores.
