This upgrade/build is a very long time coming and now seems like as good a time as any to finally complete it. The main purpose of my build is to run DotA 2 in 1080p@60fps on max settings and run other programs (which I've never had a problem with, so I'm not concerned about them).
Apart from DotA 2, I regularly play Dark Souls 2. I would also like to play other games in my library (such as Chivalry, Gothic 3, Fallout Series, Witcher, Far Cry, Battlefield, etc) but max settings and 60fps are not necessary for these.
The only thing I might change at this point is the case. I'm wondering if I can make this build work in a BitFenix Prodigy - I also have read that the Prodigy M has a better layout and that I should probably go with that. I'll have my OS and DotA on the SDD, maybe Dark Souls 2, with the rest on the HDD. I might overclock - should I use a different motherboard?
The build has exceeded what I originally expected to pay for a build but after my research I feel like the expenditure is necessary and I can afford/justify it. Keep in mind these are Australian prices. My other peripherals I was considering was a Ducky Zero (Brown) and a Cougar 200M, Razer Deathadder, Stealseeries Sensei/Rival or Logitech G502 mouse.
