This depends on what your current needs are, and what you plan to do with your computer in the future. If you are mainly using your computer for basic tasks such as web browsing and media streaming, then upgrading your RAM might be the best option. You may want to consider upgrading both your RAM and processor if you’re planning to use your computer for more demanding tasks such as gaming or video editing. It’s best to research your specific needs and determine what combination of upgrades would be best for you.
