Help noob build computer

I need some help selecting computer parts because i've never built a computer before. I've got a list of everything i need but when i go looking for it on Newegg i just feel overwhelmed. Please recommend parts for a high-end gaming PC. Also, i'm trying to stick to a budget of about $2000, but i'd like to be able to run something like Crysis near max settings.

Don't build a high-end gaming pc. In half a year your pc will be old, or at least not high end anymore. It's a waste of money, buy a pc with components that are >6 months old, it'll save you money and you won't be able to see much difference anyway
