Fortunately, companies like Alienware and CyberpowerPC are able to offer prebuilt PCs that not only look unique but also house cutting-edge components like the top-tier NVIDIA RTX 4090 graphics card. While buyers can often save money by carefully selecting their own components, it's still a fairly time-consuming process. When it comes time for a new rig, the debate inevitably surfaces about whether it's wiser to assemble a system from custom parts or purchase the best prebuilt gaming PC.
