If you’re using an older computer or a computer that came without a dedicated graphics card (GPU – Graphics processing unit), you may have considered getting a more powerful GPU. An upgraded GPU will let you:
- Play games at higher resolution, detail, and frame rate
- Play HD video without stutter
- Use two or more monitors (helpful if you can only use one with your current setup)
- Speed up photo and video editing
In this guide, I’ll show you the basics of finding out what your upgrade options are and how to install a new graphics card.
Windows Forums member, Bert_H, asked the following 
The windows Clipboard is where the computer temporarily stores text, files, graphics etc. that your CUT or COPY resides until you PASTE the content into its new location. Up until XP you could easily check the contents of your clipboard using the ClipBoard Manager. For some blurry security reason Microsoft removed this nifty application from Windows Vista onward. If you miss this feature, fear not – the fix is a simple one. If you have access to a Windows XP installation (XP mode anyone ??) you can copy it to your Windows 8, 7, or Vista machine.
First there was VGA, Video (or Component), S-VHS and Scart connectors. All of which use analog signals. Analog signals means that we don’t need any kind of computer to process images (and sound). All we need is old-fashioned electronics or even just a piece of paper and a needle. Today when “everything” has gone digital we have got two new standards called DVI and HDMI.
