It is safe to say that particular CPU is one of the fastest available, as far as a CPU goes for raw speed.
Your question can have extremely wide ranging answers depending on a large number of variables.
Exactly how fast it loads a program or boots depends on the OS you are running, hard drive speed, memory speed, amount of memory, and other components.
Once the PC has booted and running, how fast programs load depends on how you have your system setup. What and how many programs/services you have running in the background. Even a very "fast" build can be completely bogged down by bloatware, adware, and other tasks running behind the scenes.
