Right now is a really good time to buy RAM as it's very cheap as in years past.
Just make sure you buy the correct RAM as some MB won't support all 16 Gb of certain types of RAM. Be sure to check the QVL first.
Thanks JD. That's where I'm running into the problem. The QVL on this board is very lacking in info. I could stick with 8gb for now, there's a Corsair package, 8gb, that's approved and more importantly, available at the 'egg.
