Hi! I have a low-mid-end PC that should run games like Fallout 4, NBA 2K16, GTA V well on low options but it does not.
Components:
Motherboard : ASROCK N68C-S UCC
RAM : 4GB DDR3 1600Mhz
CPU : AMD Phenom II x4 945 3.0 GHz
GPU : AMD Radeon HD7750 1GB GDDR5

What is the problem? Can you help me please...
