So I really would like to get your opinion on this. Seems that it's time for an upgrade. What do you think is my ABSOLUTE MINIMUM REQUIREMENTS to build this machine?! Something that would give me the option of playing the new released games as COD and Battlefield 4. And please give me your opinion also on should I build my own or buy a pre built one. And if you see something within the $500.00 budget please send the link in the answer box. Thank you for all your help.
