Hi, I am looking to purchase my son a desktop computer for Christmas, but have no clue what i am looking for... He wants a gaming PC. He typically plays COD and GTA on XBOX, and i am assuming those would be the same type of games he would be playing on the PC. He would also be doing some virtual schooling on it, so he would need some storage for assignment files... but i would presume anything capable of gaming would be able to handle that. Any help on what a good gaming pc entails, would be greatly appreciated!!
