The October 2013 issue of MPC has a really good article about bitcoins and mining for them. One thing I wished it would have covered is how many BTCs a person could anticipate earning with a typical computer. Since they are getting harder to mine and more people are doing it, I'm guessing you won't mine that much. Maybe someone on the board with experience could shed some light.
Bottom line: AMD's GPUs are significantly better at mining than nVidia's; so if you plan on doing serious mining, you should get an AMD GPU. In fact, you would be better off building/buying a system dedicated to mining. As to your selection, the mobo supports SLI, but I can't tell if it supports crossfire (but I don't think it does).
Disregarding bitcoins, the 780 or Titan would be ideal for gaming with that type of monitor.
Not sure why you need 16GB of RAM, but you may want to check prices before you buy - $160 seems high for 16GB.
Oh, the PSU should be ok but you may want to run use a PSU calculator to make sure it will be enough. I tend to get more power than necessary, but if it were me and I was getting a 780, I would probably want 750W.
Hope this helps.
Thanks for the response bgdog
. It was actually the October issue that piqued my curiosity with bitcoining
. I try to be as pragmatic as possible in life, so when going for this build I think "I want to accomplish as many things as I can in one build."
From what it sounds like, it seems like throwing efficient bitcoining in the mix and I should be happy with what I have.
As to the 16GB of memory...In my line of work I do a lot of SQL, .net, C# and now tabular model (which is in memory olap processing) so my need for memory is growing. I may actually consider going 32GB just to future proof myself for what I do
