I have a very similar setup to yours see below:
Rock Solid for me.  I have friends with thier builds confused with enby in regard to the cost and performance.  The SSD makes a big difference.  I use mine for the OS/Audio apps/VST.. I used my 2TB for other data and content. 
 
I think that you have made a good choice and if you feel that you need an extra kick without addtitional cost..  these boards stats can easily be modified to run beyond stock.  Especially with the 2600k.. I believe that you will enjoy the headroom the system gives.. I know that I am...

Another thing I thought of that many people don't do with a new board (often the manufacturers as well) is to check out the EMPTY slots are all working once you are up and running.

For example if you only have one bank of memory populated at purchase time check out the memory in the slots for the other bank too.  PCIe slots are they all working?  PCI too if fitted and you plan on using them ever.  USB headers and drive sockets too are all worth checking on delivery.

It's pretty straightforward usually to swap out a board which is DOA, the returns process seems to get more complicated if you want to add another 12Gb or PCIe card a year or so down the line when you find out one of the slots is kaput at that time.

Static is a killer too, even when the damage doesn't show up straight away, it only costs a few bucks to get armed with an anti-static wrist band in the first place.
