Probably a typo with "i7 3370". I guess you meant the Core i7-3770K CPU, which is over $300 U.S. alone. A decent 23-inch monitor will cost at least $150. I am sorry, but the bad news is a high-end build will be well over $1,000.
Otoh, the good news is that you probably do not require a high-end rig. Tell us what you want to do with proposed build and we may be helpful. Specifically, applications and gaming. Re gaming, what resolution(s) and what are your needs/expectations for gameplay and settings.
