I was planning on making some additions to my PC and I would like some opinions. I run an i5-4460 and a 500w PSU. My additions (http://pcpartpicker.com/p/Pg9TVn) were just going to be a GPU and Case but I decided that I would buy a MOBO just for shits and giggles (plus I am not sure my current MOBO has the connections for a 970) but they stopped selling the Sabertooth Z87! Any suggestions or opinions on my additions?
