A team at the Georgia Tech Research Institute has determined that passwords 7-10 characters in length are woefully inadequate. They recommend that everyone increase their passwords to at least 12 characters comprised of a mix of upper-case and lower-case letters, along with digits and special characters in order to protect from brute-force attacks.
The reason for this being that the processors in widely available and affordable graphics cards have increased in performance at a drastic rate. Modern GPUs contain many pipelines for parallel processing which allows for rapid rendering of millions of vertices dozens of times per second. Someone looking to brute-force your password can harness this cheap, available power to quickly crunch through all possible combinations for 7-10 character passwords.
