Yo !

For my personal opinion, just dont just jump ship when you have a better paycheck. You need to look at your career in a long term wise as you've already mentioned that your current job have alot of potential and will be expected to be promoted to manager in 3 years time. It's good that your company actually plan you career path with you and will be moulding you to be a manager material instead of paying you more without proper guidance on your path.

Besides, there is always a risk of you contract being terminated after just 6 months if you jump ship. Trust me, I am also a master holder and I was in your shoe before. My current job is my first job and only pay me RM1850 for my master degree and I was disappointed just like you now. BUt later found out that it actually takes 3 to 4 years for one to learn the ropes and ready for managerial level's responsibility. Now is my second year with the co and I must say I am on the right track at this moment... and also the pays gets better and better .

Master degree is nothing if you could not perform and expect to be paid certain amount of money. If you have the capability, management will eventually recognise your ability. With the master , you will be on a fast track to for promotion. That is just my 2 cents lar.
