How to distinguish a good video card from a high-end video card. A good measurement of a video card’s performance is the frame rate. This rate is how images are displayed per second. Games that are fast action require a 65 frame rate, whereas other less intense tasks can be done with a 25 frame rate. Another factor is speed. The hardware of the card affects its speed. While there are a few tricks to increase speed, the computer’s speed will also affect the video card speed.
