What is all that VRAM in the imac used for?

[hugodrax]

The model I ordered comes with 8GB of VRAM (27inch AMD 580) What is the memory used for? Is it actually used by the apps like Final cut pro?

FCPX can be one of the few apps now, but Metal 2 programming guidelines seems to point out that more VRAM is going to be used for different kinds of buffers to reduce latency while running demanding apps. Most likely Virtual Reality is going to be quite demanding in this regard... but as of today, mostly Windows games will benefit of the VRAM.
