If you've ever wanted to know how NVIDIA's G-SYNC technology works and why it's important you'll want to check out this interview I did with William Tsao, the product manager for the team.
The general gist is that the technology allows the video card to control the refresh rate of the monitor which means an end to tearing and other graphical glitches caused when the video card and monitor get out of sync. It's pretty cool stuff and I'm interested to see it in action when it hits product later this year.
