Call of Duty: Black Ops 4 will required either a i5-6600 or a AMD Ryzen R5 1400 accompanying a GTX 1060 graphics card or the new AMD Radeon RX 570. We also strongly advise 16GB of RAM to get some reliable frame rates at 1080p, as our PC a few years back kept crashing with 8GB on a COD title, and COD BSOD was fixed with some extra RAM. Min specs for COD BLOPS 4 will be along the lines of an i3 CPU with either GTX 1050 or RX 460 GPU and 8GB to get around 30FPS at lower resolutions.
Call of Duty: Black Ops 4 is rumoured to be the new Call of Duty game under development at Treyarch. It is reported to return to the modern era with boots on the ground combat.
