I'm pretty new to PC gaming, but I would never do what this guy did. My friend is building an $800 system, and blew most of the money on the motherboard. My $500 system I currently have has a GTX 1060 (3GB) and he is using... A GTX 1050 (2GB.) Not the greatest decision for a system of that price, right? I told him he made a mistake doing this and the only response I got was "Well my motherboard supports SLI, unlike yours." Even though I never even dreamed of using SLI in a $500 system, nor do I think it's possible unless you shop used. This guy is a complete dumbass lol. (Plus he's built systems before, this $500 one was my first.)
