You are so loaded with $ $4000 USD will get you almost anything..and since you're just starting off, you won't be disappointed with anything you get.

My word of advice is don't blow it on silly stuff like: carbon cranks or carbon handlebars. Don't waste it on going Dura Ace / Record either when a step or two down will be just as good.

Spend it on a very very nice frame and a nice set of wheels
