Didn't Intel recently mention their future GPU's would be supporting this as well? Hmm....

Yeah, Intel will start to support generic adaptive refresh rate technology starting with their Gen 11 iGPUs which is either going to release later this year or next year if they suffer some more 10nm logic node delays ... 

Does that mean I don't have to buy G-Sync monitors anymore?

If you have either a 10 or 20 series video card then absolutely ... 

The only benefit G-sync brings are it's tighter standards but as long as you do your research regarding the many options out there supporting adaptive refresh rate implementations it can be circumvented. It arguably pays a high dividend in the end since generic implementations of adaptive refresh rate are future proof which means tons of devices in the future are guaranteed to work with the technology, this is not so for G-sync ... 

Future proofing isn't really something I do with my PC hardware. The only things I want or expect to last longer than 2 years is my current SPC and my TV. If at some point my G-Sync monitor isn't compatible anymore with whatever I'm doing it's time for a new one either way.

The important part would be that I am not limited by G-Sync and have a greater variety once I buy my next monitor.

Here's a nice infographic ... 

Basically, Nvidia will automatically enable variable refresh rate with these approved displays in their drivers that don't implement G-Sync but you can still enable VRR manually in their driver settings with displays weren't approved ... 

No, now you have to buy a G-Sync-Ultimate monitor if you want the best.

Zero chance the boost rate of every processor is neatly spaced 800 MHz away from the core clock, no exceptions, and that the highest clocks, but without the highest TDP, are found in the cut down 12 core part of all things. Not to mention we're still far from release. It smells like something guessing about their dream specs.

But I get that AMD is often the target of wishful speculation, they're the underdogs who supposedly bring more value for your money to the table, so it's natural people become emotionally invested in their products.

The moment VRR (almost based on AMD's Freesync) became the standard, Nvidia had no choice but to adopt it. They still have the G-Sync 2 version for HDR content to sell premium monitors.

Oh, and it's worth noting that, even if a monitor doesn't pass Nvidia's certification, it won't mean that it won't work. We'll still be able to enable it from the default off mode.

You're right, people want AMD to almost obliterate Intel after so many years.

In any case, we'll probably know how much of true there is in that rumor in a couple of days when AMD makes its CES presentation.

Still happy with my current G-sync monitor, so I've no reason to get all giddy for any sort of Free-sync monitor anytime soon. Maybe in 3-4 more years, hopefully when the quality and standards have quadrupled since then.
