PCI Express Graphics cards connect to the motherboard inside of a PC.
PEG stands for PCI Express Graphics. It is a video card specification that helps modern PCs better render and play intense graphics and games. The PEG is tucked away on the inside of a PC along with other critical hardware components. It is fair to say that the average PC user rarely explores the inside of a desktop or laptop computer. However, you might feel compelled to open the PC’s case to inspect the graphics card if you are having performance problems. Instead of going through that hassle, you can use a native utility in Windows to numerically measure the health of your PEG.
1. Click “Start.” Type “Windows Experience Index” in the search box at the bottom of the “Start” menu. Press “Enter.”
2. Click “Rate This Computer,” if this is your time using the tool. Click “Re-Run the Assessment” in the right corner if you have used this tool in the past.
3. Wait while Windows tests all of the hardware and software components on your PC, including the PCI Express Graphics card.
4. Find “Graphics” and “Gaming Graphics” under the “Components” column header after the testing is complete. Look across to the “Subscore” column. The highest possible score for Windows Vista is 5.9 and for Window 7 it is 7.9 –the higher the better. For both operating systems, if your subscore is below 1.0, your PCI Express Graphics card might have performance problems.
