NVIDIA rolled out an upgrade kit that lets you retrofit your ASUS VG248QE monitor with NVIDIA G-Sync technology, letting you take advantage of the display's up to 144 Hz refresh rate for some incredibly smooth visuals (we've seen G-Sync in action ourselves, and it works like it should). The kit is a PCB with a handful of headers. You can either retrofit it into the monitor's body yourself (a DIY video is posted). The G-Sync kit is priced at US $199. The DIY installation video follows.
