Tom, BlueStacks is an Android Emulator that allows Android Apps to run on a PC. The only problem with these is they consume a lot of RAM and increases the CPU usage. This slows down your system and reduces the system's performance. It also uses the Graphic Card that is available on you PC.
That said, it will run well on your PC, especially if your PC is a powerful one. PCs with generous amounts of RAM, fast CPUs, good graphics cards, and fast solid state hard drives will work great.
If you have a PC with minimum resources your experience may not be so good.
