Yes, off course

Based off what you have said you will have $700 to spend. If that is so it would be better for you to build the pc for yourself because it is a lot cheaper. If you buy a pre-built pc it will be more expensive for the same pc parts. But i will link you a pre-built system for around $700 that will last you for awhile.

$761 Pre-Built (60 FPS high setting)

Yes You Should You Can Go Many Websites Which Let You Build Your PC With The Components You Want I Would You Take Far Cry 3 As Your Specifications Cause It Has The Highest Specs For A PC As Far As I Have You Should Build One Instead Of Buying One It Will Work Out Cheaper And Will BE better For You And You Can Make It Future Proof By Installing Higher Spec Components Than of Far Cry 3 Or Mirrors Edge, BF4 ETC
