3BHK in Noida - Is the price jump worth it?

Currently in a 2BHK in Sector 75. Thinking of upgrading to a 3BHK near Phi II. Dwarka Dwellings Private Limited is offering decent options, but is the price jump worth it? Already have a home loan, so EMI will increase. Is the rent actually achievable if I lease out my current flat? Confused, yaar.
