BUT!! .. (and there's always a but) .. does your monitor support truly wider gamut colour space?
i.e. you really need a high quality monitor AND more capable graphics card(if you don't have them.
Dunno your system specs, but there are ways to see if your hardware can support higher quality settings.
So unless you are 101% sure that your computer hardware is capable of rendering the wider gamut of colours, I'd say stick to RGB.
Reason is, if you're tweaking and twiddling colours, and behind the scenes you do get better colour fidelity(that is in the actual file) .. the lowest common denominator(either your monitor of GPU) may be showing you(rendering) something completely different.
It's the WYSIWYG effect.
With all suped up, high quality hardware, you will most likely see the benefits.
But lets say your monitor is only a 6bit(colour) model, it can't display the colours in the file .. so you don't see what you're getting.
