Doing a /create is going to be MFT lock-bound. You probably won’t get any improvement above /MT:2. You are probably far more interested in IO Total than anything else. A single thread can be holding a 64 MB buffer, but depending on the driver and IO controller there may be darn close to zero processor usage (and on others it could have a huge impact – it all depends).

While doing a /CREATE only run, it seems to not have any impact on performance (based on CPU usage in taskmgr). What's your favorite thread count? LOL
