Definitely. I would much rather just buy a better gpu! The lack of range in the variable refresh rates is a big part of why I wouldn't buy one of these type of screens yet. I hardly see any frame tearing with my panel at 120hz and no vsync anyway. I'm not sure these screens make much sense at this point in time for those that would benefit most. The money would probably be much better spent on more powerful hardware..
Edit: Although, quickly glancing back at this review, it says freesync is supported from "35-90Hz". If that includes every single number inbetween, that's actually pretty damn good! I would be tempted by that if I cared more about syncing frames
But as I say, the sight of screen tearing is very uncommon and minimal with my current setup, so I would still go for better hardware instead..
