I don't know much about this, but I want to a gaming pc around $1k3 to $1k7 ( not include monitor, mouse, keyboard ) that can run high graphic games like COD, BattleField,...
Thanks!

TBH, you could easily save money on a system that would run COD and Battlefield on Ultra, and get the price down to ~$1000, by getting an i5, 8gb ram and a cheaper case, but within your price bracket, this is a decent build
