I just increased the memory to 16GB and I'm looking at the case right now. I'm fighting with myself to not go overboard and get the 780TI with SLI, making this a 3000+ dollar build. I think I'm going to have enough control, but will probably invest in upgrading when the 800 series comes out.
As for headphones, do you have any recommendation? I have a pair of Turtle Beach headphones that I use for my PS3/4 that would work fine, but I'm wondering if there is a pair that would do better.
Thanks!
