If you are getting started with Raspberry Pi for the first time, it's recommend to take these starter kits instead of only the Raspberry Pi 3 Board:
The Raspberry Pi 3 Model B builds upon the features of its predecessors with a new 1.2GHz 64-bit quad-core ARM Cortex-A53 CPU processor on board to increase its speed (~10x the performance of Raspberry Pi 1).
It also features WiFi and Bluetooth Low Energy capabilities to enhance the functionality and the ability to power more powerful devices over the USB ports.
