Core i3 is sufficient actually, but let's see if we can fit in an i5 in your budget (assuming it's ~ RM2.5k). Hmm, important thing is the PSU can provide sufficient power to power up the rig. A 500W is enough for your case. GTX 650 Ti Boost is on par with HD 7850.
Intel Core i5 4430 – RM569
Asrock B85M Pro4 – RM289
Corsair Value Ram 4GB DDR3 1600MHz - RM119
Leadtek GTX 650 Ti Boost 2GB – RM599
FSP Hexa 500W - RM149
WD Caviar Blue 500GB HDD - RM159
Cooler Master K380 Casing - RM149
Lite-On 24x DVDRW – RM59
Viewsonic VX2336S 23" IPS LED - RM479
Logitech G100s Keyboard - RM119
Total - RM2690
