Hello.

My friend going to  built a new gaming pc, he ask me for the spec, but im a lit bit noob about that  , so can all sifu help me with this 

Purpose : Gaming PC
Budget : < RM2000

With Keyboard and mouse

Monitor : (if possible) Suggest me.

Hoping for the pros to help me 

Thankyou very much ! 

  i thought hardisk is purely for storage only? larger space increase performance? i dont usually download movie and song into my pc.. i usually prefer streaming.. so 500gb is already much more i can use          tqtq for ur patience~

no la, i think he meant more space is better. as for the performance part, its about the processors

Thanks marfccy sifu.. okay.. finalize what im getting first,,

This is a quote I got from ACI Karamunsing KK. Numbers in red are from Jayacom.

Intel i5 3470 -  599 (555)

Asus B75 - 249 (245)

Kingston 8gb - 179 179

WD 1TB - 229 192

Saphhire HD7850 2gb  - 889 599
The price for the rest of the components are insignificant.
Other than the graphic card, the rest of the products seem ok.

Just a reference for KK people about the price.

PC Expo is in Midvalley this weekend.. probably can cheaper price there? just in the right time~     

Depends on your game resolution and graphic settings. Game like dota2 should hv no prob to max all setting.
Hmm from i5 3470 to i5 3570 not much increase in performance, try 1TB hardisk at around RM199.

Ouh okay,but how much it will cost if I want the owner assemble the part for me ? I dont want to do it myself lol

Most of the time assembly is free of charge if you are buying all things from them.

well maybe you can change 500gb HDD to 1TB

500gb WD/Blue- RM164

-->1TB WD/Blue - RM199

TOTAL would be RM2001

edit:

sorry for asking too much 
how much need to add if change to i5?
maybe i5 the most stable one and affordable one.
