Hi Sir,I am Bharath fom India.The 600$ Budget is a good one for Gaming.I can give you my specs too.Please consider this.
This is an AMD Build as for your Budget I feel AMD will be the Best ! Because AMD is always known for providing better Entry-level Gaming CPUs
CPU- AMD 3.5 AM3+ FX 6-Core Edition FX-6300 (FD6300WMHKBOX) Processor
CPU Cooler- Cooler Master Hyper 212X or EVO (X has Better Cooling,EVO is Quieter)
Non Over-clocking Motherboard - ASUS M5A78L-M/USB3 Motherboard
Overclocking Motherboard - ASRock 990FX Extreme9 AM3+ AMD 990FX + SB950 SATA 6Gb/s USB 3.0 ATX UEFI BIOS
RAM - Kingston HyperX DDR3 8 GB (1 x 8 GB) PC RAM (KHX1600C10D3B1/8G)
GPU - Sapphire AMD/ATI Radeon R7 260X 2 GB DDR5 Graphics Card
SSD - Samsung 840 EVO 120 GB Desktop & Laptop Internal Hard Drive (MZ-7TE120BW)
PSU - Corsair SMPS CX500 500 Watts PSU
Case - Cooler Master Elite 431 Plus Mid Tower Cabinet
OS - NIL (I hope you already have one)
The FX 6300 is the same price of that i3-4130 but has 6 Cores whereas the i3 just 2 puny cores.The Samsung SSD EVO 120 GB is way Faster,Quieter and More Reliable Drive than the HDD.You don't need a 600w PSU so waste of money.The R7 260X is slightly better than the GTX 750 Ti ! Please get the R7 260X.
All this will come near to your 600$ Budget
If you feel,My build Concept is better,Please Select mine as your best answer
Thank you
