CPU = processor itself only 

Should call it as 'rig' instead and the situation is a bit different in your case because your budget can fit RX470 8GB + i3 or RX460 4GB + i5 but there is no actual/real life benchmark or review yet, we are getting it much earlier than other country this time around 

i5 + RX460 (weaker GPU with stronger CPU)
Intel Core i5 6402P - RM 707
Gigabyte H110M-DS2 (D4) - RM 249
Corsair 8GB DDR4 2133MHz Value RAM - RM 131
Sapphire RX460 4GB GDDR5 Nitro - RM 689
WD Blue 1TB HDD - RM 215
FSP Hexa+ 550W - RM 189
Tecware Alpha - RM 199

Total: RM 2534 (Techview price inclusive of GST)

i3 + RX470 (stronger GPU with weaker CPU)
Intel Core i3 6098P - RM 437
Gigabyte H110M-DS2 (D4) - RM 249
Corsair 8GB DDR4 2133MHz Value RAM - RM 131
Sapphire RX470 8GB GDDR5 Nitro+ - RM 1139
WD Blue 1TB HDD - RM 215
FSP Hexa+ 550W - RM 189
Tecware Alpha - RM 199

Total: RM 2559 (Techview price inclusive of GST)

RX480 is between GTX970 and GTX980.

My prediction:
RX470 is between GTX960 and GTX970 (or R9 380 to R9 390).
RX460 is between GTX950 and GTX960 (or R7 370 to R9 380).

RX460 is more worth in my opinion, 4GB version of RX470 is due to arrive in Malaysia soon as well at RM 989.

May I know what games you are going to play (or currently playing)?
