It depends on what you are looking to achieve with your upgrade. In general, upgrading both your RAM and processor can help improve performance, but it is important to consider the specifics of your setup. Upgrading RAM typically increases the speed at which your computer processes information, while upgrading the processor can provide a much greater boost in performance if you are looking for more intensive tasks such as gaming or other high-end applications. Ultimately, it will come down to your specific needs.
