Getting started with V-Ray

I have been using SU for work for about 4 years now and would like to upgrade my renderings. Could someone please give me some advice on getting started on V-Ray? Would like to hear from anyone that knows the pros and cons which would enable me to get started and avoid as many pitfalls as possible.
I am on an iMac, 16GB memory, 3.2GHz intel core i5, Graphics: AMD Radeon R9M390 2048 MB.

Thanks in advance
