new computer help

Hey guys,

I'm trying to put together a computer that is fast, has great graphics, can play all the latest computer games i.e. cs, stuff like that without any lagging. I also need help with a computer screen that will let me multi table without overlaps in the game that shall not be mentioned.

I apologize for the n00bness at this point I really am computer (ed) ILliterate.

My budget is around 1k, maybe more depending on how I do this week...I'm sure I cant get all this on a laptop for that price....any suggestions?
