Water cooling isn't really necessary for an enthusiast tier PC. People who have no limit to their budget tend to buy into water cooling for aesthetic reasons, or to reduce fan noise, or simply for bragging rights. Overclocking enthusiasts (people who compete to get higher benchmarks scores) may have some practical use for water cooling, but it's fairly pointless if you are only interested in high-end gaming.
Water-cooled GPUs are generally able to overclock further than their air-cooled counterparts, but they are quite a bit more expensive. Sometimes they might be worth the extra cash, sometimes not, it usually depends on the card.
Not that I'm planning to (since my motherboard probably can't handle it), but what about NVIDIA SLI or AMD Crossfire? Would I need liquid cooling for either of those?
No, a well ventilated case is probably all you need for SLI or Crossfire. Both SLI and Crossfire have significant drawbacks that NVIDIA and AMD can't seem to fix (micro-stuttering is a big one). Also, it isn't like adding a second GPU gives you an additional 100% GPU power either - excellent SLI or Crossfire scaling is like 85% at best and is highly dependent on the game engine as well as drivers.
When you consider the extra costs of adding a decent SLI or Crossfire compatible motherboard, a high rated/high wattage PSU, a second GPU, a powerful enough CPU to drive two GPUs, and most likely additional case fans to keep temperatures down...I would almost always opt in favour of buying a single more powerful GPU.
The video below shows how well a FX4300 can run the Witcher 3 at Ultra Settings when paired with a GTX 980Ti...the RX480 won't beat a a 980Ti but it will at least match a 980, so you will still get very decent framerates (45-50 FPS+) at high to ultra settings. I have a hard time seeing much visual difference between 45 to 60 FPS and IMO for a RPG like Witcher 3, you really don't need perfect 60 FPS. Also, there are a lot of Ultra settings in the Witcher 3 that eat into FPS, but will provide little to no visual improvement (especially at 1080p resolution).
