That's not bad, Cybermonk.  I like what you did with the text there.  However, you might not need to subdivide at all after cutting in the text, if you can chamfer or bevel the edges with enough segments, and maintain a rounded curvature.  In this example, I've quad-chamfered the tetrahedron with 4 rounded segments, and it renders perfectly smooth without subdivision.  Obviously, I don't have the text cut in here, but the same principal to smoothing edges should apply.  Also, check to see if your package supports edge-smoothing shader effects, which could be used to help fillet the edges at render time, and save some unnecessary geometry.
