So for my first PC to introduce me into the world of PC gaming, I wanted something budget friendly and simple that can run most games. I did my research and decided to pick a pentium 4 as my processer because it's super cheap on ebay. I wanted to spend the most money on a graphics card so my games have good graphics. I decided to go with an evga 1080. When I try to run minecraft and roblox it lags really bad. what did i do wrong? ps. i also have 2 gigabytes of ram.
