Whether you’re looking for a new laptop or you want to upgrade your existing computer, one of the most important considerations for performance is the amount of RAM it has. While most computers include 3GB or 4GB of RAM, that may not be quite enough depending on what you expect your machine to do.

RAM is the memory that your computer or laptop uses for startup and running the operating system and apps. This means that the lower the amount of RAM available, the slower your system will run. Additionally, it will also affect how your apps and windows run while you are working and playing.

If you need a laptop that can handle streaming music or videos while you work in multiple apps, the Lenovo G50 80E30181US 15.6-Inch laptop may be exactly what you need. It features an AMD A8 processor and 6GB of RAM, ensuring that the Windows 8.1 operating system and all of your software loads quickly and performs at its best.

For some, a 6GB RAM laptop might not offer the performance and speed they want in a new system. For those who fall into this category, the Toshiba Satellite C75D 17.3-Inch Laptop with an A6-6310 AMD Quad-Core is sure to impress. This laptop includes 8GB of RAM, making sure it can handle everything you need to do, including those graphic-intensive games.

If you already have a desktop and just want to make it perform better, the 6GB RAM Kit by Crucial will have you up and running faster than ever. The kit includes three 2GB sticks of DDR3-1600 240-pin memory. Adding this to your desktop will make multitasking faster and easier, and will make waiting for a program to load a thing of the past.

If your computer or laptop is running sluggishly, upgrading to 6GB of RAM will make it feel as if you’ve bought a new, high-end computer.
