The best choice in determining how much memory should I use a lap top

Why not use a lap top video card like a desktop? and why always use a lap top memory sharee (discreate) for image and data processing needs of video. Of course you already know the answer ... is to overcome the limitations of existing places in the room the body of a lap top. You can imagine if a lap top using the video card ... will certainly take a lot of places and instead will make even greater burden ... and this will eliminate the concept of lightweight, practical and high mobility. The concept of on-board VGA has long been used by desktop computers, let alone in order to save costs, each vendor trying to integrate mainboardnya with VGA. However, the pattern of working the machine with the concept of on-board VGA will be very annoying when the RAM memory available is very small. Regular RAM will be shared with VGA memory, this will make the machine to be slow in receiving and sending data from the processor, coupled with the limitations of most high speed 7200rpm hard drive, this will create congestion data between disk and processor. To solve the problem, when it has been created Flash Disk Storage has better speed than a disk.
Currently the memory requirements in addition to using the concept on board the mainboard, now inside the processor has started doing built in a special memory for the video card, as did the 2nd intel (intel HD 3000). Still, this concept requires a large enough RAM to share in the allocation of memory for image data processing and video data. AMD still uses the concept of onboard with ATI Radeon, or its AMD Radeon. While Apple has Tehnology Thundherbold. Here we can see the need for RAM is very dominant once, when it is not quite 1GB DDR3 RAM, but at least 4GB of DDR3 which should be built in a machine in the lap tops. And its benefits will be felt if you use an application last games, watch HDTV, video on Yutube rendering, video editing for entertainment will feel very light and smooth. Ideal for a lap tops is 4 GB and 6 GB for today's computers.

Can you see (here)the current lap top no longer use 1 or 2GB of memory anymore, because all the adjustments with regard to technological developments and hardwere latest softwere increasingly sophisticated.
