2 GB of RAM makes it a much more enjoyable experience, as I've found when I upgraded the RAM in my Dell Latitude D430 notebook. When browsing online with multiple tabs open, 1 GB of RAM can make it lag and otherwise just a poor experience. If you have Windows Vista or Windows 7 installed, I would recommend having a minimum of 2 GB of RAM installed. If you are brave enough to go online with XP this day and age, then bump on up to 2 GB of RAM for a smoother experience. For XP, since support for it has ended, I don't even recommend using XP online anymore, unless you are very diligent about using anti-viral and anti-spyware applications to protect yourself. If you have Windows XP installed and typically use it for light activities such as word processing and spreadsheets, I would highly recommend having at least 1 GB of RAM installed. Yes, upgrading your hard drive and replacing it with a larger and faster one would help this some and perhaps even quiet the thrashing as all of your applications are still using virtual memory, but it won’t get rid of the reason you need to use virtual memory so often or so much. Virtual memory is great in that it allows us to have more than one application open at once, yet it is so terribly slow as it is nothing more than some amount of space on your hard drive, which is tremendously slower at transferring data than RAM is. The less RAM you have installed, the more applications you have open at once, the more your PC or Mac will have to rely on virtual memory to keep things going and the slower your computer will feel. Multitasking, or having more than one application open at once, complicates this further. If you've heard of virtual memory or have a vague understanding of what a page file is, then you must know that the reason for their existence is because most computers never had a large amount of RAM installed and the operating system had to have some way to support its own needs for memory and the needs of any applications. Modern operating systems and applications perform best with an abundance of RAM installed on a machine. Let me emphasize this as much as possible, you can never have too much RAM installed in a system. Why Shouldn’t I Upgrade the Hard Drive or Processor First?
