To upgrade from a single-core processor to a dual-core system, replacing the existing processor is essential. This is because a dual-core processor has two cores integrated into a single chip, allowing it to perform multiple tasks simultaneously. Simply adding another processor to the system would not create a dual-core environment, as most motherboards are not designed to accommodate multiple processors unless they specifically support multi-processor configurations. Upgrading the motherboard alone does not suffice if the processor is not upgraded accordingly since the motherboard's capabilities are only part of the necessary changes. Increasing RAM capacity does not influence the core count of the processor either and primarily affects the system's ability to handle more tasks concurrently, but it does not directly upgrade the processor itself. Therefore, to achieve the transition from single to dual-core performance, replacing the existing processor with a dual-core variant is a fundamental requirement.
