hi sifus, I plan to get a gaming rig which can last about another 3-5 years. if possible, must be able to play games in high settings. (ultra settings for bf4)

CPU: Intel Core I5 4570
MOBO: ASUS B85M-G
RAM: 8gb ddr3 1600mhz
HDD: 1tb hhd
Chasis: CM K350 Casing
PSU: FSP HEXA 500W PSU
ODD: dvdrw
GPU: R9 270x or GTX760(prefer gtx760 if meet budget)

my budget is rm2500. refer to the spec above, is rm2500 enough or I have to top up? or do u have better suggestions?
this budget does not include lcd, speaker, etc. I have them already.

Thanks in advance! =D
