Ive never built a computer before so i dont really know what parts are good and what is bad to build a really good gaming computer. Idk if i want a pre built or build my own sooooo... if someone could send me parts from newegg i want to be able to play any game on it with high settings hopefully.
I can't really recommend all the parts...but with $1600 you could get a GTX 580. 2500k should also be fine for gaming...as you could save $100 if you got a 2600k...which is good if you do heavy video editing etc.
I will say this though, DO NOT buy prebuilt. If you build one yourself, you can save yourself alot of money. It's not hard building yourself.
