What would be the point of that? It is a QHD IPS panel with a known sync range. If you have a monster GPU, just get a 144Hz monitor and be done. You likely don't need Free-Sync or G-Sync if all your games play at 100FPS +.
The point is simple. If you buy a $599 monitor you won't be spending 1/4 on a GFX card.
Also, if you have a 144hz monitor, you want it to perform at all ranges below, if the game isn't maxing at a stable 144 hz, then gsync or freesync will improve the FPS tearing. If you play a game at 95 fps and it is varying frame rates, the entire point of this technology is to stop tearing.
Tearing happens even at 144hz, so no need to make excuses for FreeSync, just admit it, the limitation is bad and needs to be fixed before this is a quality tech to get behind.
