G-Sync, while proprietary to Nvidia right now, should be fairly easy for AMD to implement as well should Nvidia open the spec: It uses a standard DisplayPort interface together with an off-the-shelf FPGA (running admittedly very custom logic) in the monitor. I do believe Nvidia will license it fairly soon, much like it eventually licensed SLI to non-nvidia chipsets back in the day. If that fails, AMD will implement their own version, and then after a generation or two of feet-dragging, they'll make it a damn standard and we'll all move on.
All in all, there's nothing so proprietary that it can't be opened up right now. Just give them time to make money of exclusivity and then watch the dust settle.

Although this monitor is capable of running at 144Hz, to keep our testing more general and realistic we did most of our testing at 60Hz.

I'd have thought it's more interesting to compare G-Sync to a 144Hz standard monitor with V-sync enabled, no? In both cases you have to spend a lot of money, so it would be interesting to see if G-Sync makes gameplay significantly better than a regular 144Hz monitor. Did you guys play with that at all?
Originally Posted by ch424Sorry, I didn't quite make my point clear - if "most people" have a standard 60Hz screen now, should they pay the little extra to upgrade to 144Hz, or should they pay even more extra to get G-Sync? Is it worth the difference?

AMD has been relatively silent on the topic of NVIDIA’s variable refresh rate G-Sync technology since its announcement last year. At this year’s CES however, AMD gave me a short demo of its version of the technology.
