Crossfire question.

[itzmesloth]

I have a R9 390 from Sapphire, so I was just wandering if there is any benefit, or is it worth it to Crossfire it with a RX 480, if that's even possible.

It's not possible. R9 390 can crossfire with R9 290/R9 290X/R9 390/R9 390X. The benefits will be around 180% of your current performance in games that utilize crossfire well. Mind the heat and power consumption though, you need a good PSU to support that configuration and you need good airflow in your case.

So if I bought a 390 or a 390x for the CrossFire, what would ne the benefit of an average game, that perhaps doesn't utilize the CF so well.

This pretty much summarizes what Crossfire and SLI are, look how they perform and listen to what Richard and the other guy say. Look at the performance relativility between a single card and a dual-GPU setup, Crossfire is overall better than SLI in terms of scaling (you get more performance from adding a second card), doesn't require a bridge and is more versatile (you don't need two exact same GPUs). Some games scale well (as shown) and some games don't use Crossfire at all.
