I am looking to build a gaming computer that can run games (cod, ac, gmod, skyrim, emulators, etc.) on high or normal settings, while still being able to do simple tasks such as using Microsoft office (word, PowerPoint, Excel). I am new to this and have never built a computer before. What parts do you recommend on a $1000 and below budget? Also is it worth buying 3 monitors (I forget the term for it; I have seen some gameplay and it looks pretty cool)?
