Brother has been using this computer for about three years now. Was a definite budget build and we built it with an i5 7600k and a 1050 ti. The 1050 ti is obviously not the greatest and is starting to have cooling issues, so I figured might as well get a new GPU for Christmas. So my question is, is it worth upgrading to a more modern pair for the 7600k? Or would it be better to try to upgrade to a better Z270 chip along with a new GPU?
