low budget gaming rig

[ahmedam3]

hi, this is my rig
CPU: Intel i5-4460
GPU: EVGA gtx 750ti
RAM: HYPERX FURY 4GP ddr3
motherboard: gigabyte h81m-s2ph
PSU: Aerocool 500W kcas
my question: is there any bottle necking? and what to do ?
and if you have a similar system post you gaming performance.
thanks ahead
P.s: wasn't sure where to post it.
edit: this rig is already built but i hope the upgrade doesn't cost more than ~50 $
