OVER JUICING THE RAM OF MY LAPTOP - is it the right thing to do?

First of all really thanks to all who replied and comment to my question

Guys you all rock big time

Verdict: I am going for the 16GB upgrade and will update in next few days when I will have it in my computer while I am using it for the HD Video Rendering.

I will agree that when the Dell Vostro 3450 launched in late 2010 or early 2011 then at that time probably the 8GB Single RAM stick weren't so common, I am sure they were available though something new and expensive.

Fingers are crossed and hoping for the best
