A common misconception is that integrated GPUs are always slower than their dedicated counterparts. But that's not necessarily true. It depends on the generation of both the CPU and GPU, as well as the tasks you want to perform. If you want to do any kind of video editing or 3D rendering, you will definitely want to invest in a dedicated GPU. You'll also need a dedicated GPU if you work with graphics-intensive programs regularly or do serious gaming. These activities require a lot of horsepower that an integrated GPU just can't provide. For general gaming and occasional image/video editing, an integrated GPU should suffice.
