I kept disabling Freesync yesterday to see if I could go without it and......Nah, it's just too good.
I was using a GTX1080Ti Xtreme for 10 months with my Freesync monitor because the FuryX couldn't cut it on TWW2, while Stellaris & HOI IV has issues with Vega cards. (PDX engine issue).
The moment these were resolved I jump ship and went from 1080Ti to Vega 64. I haven't looked back.
I rather have 120 fps with Freesync (at 240W lol), than 175 fps and a screen full of tearing. (vsync no option due to input lag).
Especially some games inside towns, like WOT the whole environment was moving like a fast slideshow. (WOT doesn't have move blurring)
With the Vega 64 + Freesync is smooth and fluid.
And also we have much much better monitors, not only well prices, than Gsync, and new ones coming out also.
35" 4K HDR 60hz? Yes, at £450.
43" 4H HDR1000 10bit 60hz? Yes at < £700
ultrawide 3440x1440 100hz HDR at reasonable price sure.
55-65" HDR TV with Freesync? Yes at £1000+
And some new ones... HDR600 UW 3440x1440 144hz with 98% DCI and Freesync2? Yep. In few weeks time.

(same applies to 2560x1440).
And there is a whole range of good monitos like those made by Pixio. 2560x1440 144hz for peanuts relatively, if someone wants second rate Samsung panel.
