Why Choose a Desktop?
There are many reasons to choose a desktop. If you're looking for a powerful processor or require advanced graphics, desktops are definitely the way to go.
Furthermore, you have the flexibility to upgrade and replace components as needed. Whether you require more storage, RAM, a new network card or even a new processor, you'll often be able to upgrade your desktop without too much hassle.
Desktop PCs can also accomodate multiple monitors by including several HDMI or Display Ports on their chassis (laptops typically only support one external monitor). This, combined with their powerful performance, makes desktops unmatched in multitasking, productivity and intensive workloads.
Summary: Very powerful, expandablity, and flexibility to upgrade.
