What? It's only good if your FPS is low.. I have a GTX 980 and almost have never seen screen tearing. There is literally no other benefit for gsync/freesync. You described what a monitor is (although TV's tend to use a special panel type I forgot the name of or IPS for LG tvs), raw screen capture - why would you want image/video processing for your computer?
Any particular calibrator? I got this monitor today for work (I'm a designer) and I know it's a TN panel and not an Apple Display but want it colours and brightness to be better.
Good price. I bought the very same one back in November (Black Friday) for £259.99. I'm very happy with it.
TN panels suck. Pay a little more for an IPS or even a VA.
