According to the official system requirements, you will need at least 4GB RAM to smoothly run Overwatch on low-medium settings. Moreover, the recommended specifications require you to have 6GB of RAM. However, if want to experience a blazing fast experience then we recommend going for 8GB of RAM for your rig because aside from Overwatch, you’ll need at least 8 gigs of memory to smoothly run the latest AAA titles on 1080p resolution.   If you own a high-end motherboard that is compatible with DDR4 memory type then we really recommend taking a closer look at Corsair Vengeance LPX 8GB because it’s the king of the hill when it comes to system memory.
