I experience stuttering in like every game I play, together with screen tearing in some cases and I bought this PC like a month ago and it stutters while gaming ever since. My PC is https://www.pcgarage.ro/sisteme-pc-garage/pc-garage/gaming-serpent-v6-intel-i5-8400-280ghz-coffee-lake-16gb-ddr4-1tb-hdd-plus-240gb-ssd-gtx-1060-6gb-gddr5/ , I'm not a PC expert so could it be because of my monitor? I have a pretty old monitor, L194WT, but when I hear other friends of mine that are telling me their gaming PCs can do well with a 60hz monitor is confusing me even more... Can you help me?
