Additions!

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?

Firstly a z97 chipset is what you want to aim for, secondly the mobo isnt the issue with connections for the gpu its normally if the psu has enough connectors (they normally do)
