Don't buy the branded link, it's over-engineered and thus far too expensive. Kiwi 5m link cable will do fine.

Wireless doesn't work out of the box yet, we're waiting on an update to drop (presumably within the next week) that will provide native link over wifi. This requires a good wifi network, preferably an empty 5GHz channel only for the quest. Currently you do wireless through a programme called Virtual Desktop (have to buy the Q2 version); this comes with some downsides compared to wired including a lower resolution, and a lower bitrate meaning visible compression. How much this impacts visual quality depends strongly on the game.

Wired link requires a suitable cable, runs at native Q2 resolution (although that might be a bit hard to actually run on an RTX2070, especially with high fidelity games), and runs at over double the bitrate so there isn't much visual compression.
