When buying a system, the memory should be one of the main considerations. The highest memory that can be afforded should be chosen since, the more memory, the faster the system will work.
In addition to the basics, today’s software applications have increasing demands on the memory of the system while using peripherals like webcams, digital cameras, DVD players, USB hard drives and video games. All these need a lot of memory and so, unless there is a high end graphics video card with its own memory, the system’s memory would be shared between the processor and the graphics chip.
This, in effect, would lead to a significantly less memory of the system than that existed originally. Hence, if high end games are to be played on the system, it is good to buy expensive graphic cards with a lot of built-in RAM or built-in video memory. This would help to turn off the shared memory and free up the system’s memory for maximum power. So, buying extra RAM or high end graphics card is the safer option.
There is a maximum limit to the amount of RAM; a system can take, generally, upto eight gigs. The installed memory will be displayed in the specification of the system while buying it and the extra memory that can be installed will also be displayed in the system.
The system memory’s requirement depends upon the operating system and the applications that are used and the utility of the system. There is always room for further enhancement and the system’s memory can also be increased, if the need arises.
