there isn't a way to test for artifacts. IF you have them, you will know it. Artifacts are defined as unwanted visible effects in the picture caused by disturbances and errors in the video transmission or digital processing. You will see missing blocks in graphics, tearing, and other anomalies.
vsync needs to be enabled. This occurs with a really new video card (fast one like your getting) while playing an older game like the original half life 2 or cod 2. The game is having problems rendering properly.
overheating. insufficient cooling, bad fans, and dirt can also cause it.
power: the newer video cards have considerably different power requirements. Not only do you have to plug in a dedicated power connection to the video card itself. It also requires the ability to deliver power on the 12volt rail and sufficient wattage. This is why we suggest a quality 600watt power supply. http://en.wikipedia....i/Anti_aliasing
In digital signal processing, anti-aliasing is the technique of minimizing the distortion artifacts known as aliasing when representing a high-resolution signal at a lower resolution. Anti-aliasing is used in digital photography, computer graphics, digital audio, and many other domains
most people use 3dmark for bench marking their video cards.
