System requirement for watch online videos

To watch  online video, such as YouTube, you need a sound card at least 16-bit, and video card at least 64MB of video memory. Some old computers do not have video card built-in, which will cause videos very slow, sometimes on and off.  I recently visited Best-Buy store, I saw one computer with video card and another one without sound card, the price only 20$ difference. It is better to ask if sound card is built -in when you buy a computer.

Processor 1GB and RAM 256 MB at least, which is no problem for recent computers.  Broad Band connection at least  500+ Kbps.  You also need to install latest Adobe Flash Player for plug-in and update your browser often for best performance.
