start up graphics glitch on OS Sierra

When starting up my refurbished 2014 IMac 5k that I bought earlier this year i seem to get a graphics glitch, after having a Macbook Pro 2011 that died on me due to a failure on the graphics card I am worried this is a early sign what should I do?

Is anyone else having this?

The glitch starts about a quarter the way through the loading bar.
