You never specified what your budget is for peripherals. You said you had a budget outside of the $1500 for them, but I don't know how much that is? I also don't know your currency. It could be USD, AUD, CAD, NZD, but I'm assuming it's USD. I have tried to keep the build as close to $1500 but I don't know your budget for peripherals, or if the $1500 includes OS?

Since you'll be playing Crysis, you'll benefit from the i7's hyper-threading capabilities. As you stated, you prefer Asus components where applicable, so GPU, mouse and monitor are Asus. A 550W PSU will suffice but doesn't leave much room for future upgrades. However, this XFX 550W unit is a freaking steal at the moment. 8GB RAM will suffice, 2400MHz is beneficial, although you won't notice much difference between 1600MHz and 2400MHz RAM, so if you want to save a little, change the RAM. 1TB HDD for storage and a 240GB SSD for OS and small programs/tools etc. That should be enough storage, if not, the 2TB equivalent of the HDD in that build is only like $80 or so. Fantastic case and fantastic keyboard as far as I am aware. My cousin has a monitor similar to that(possibly that exact one) and he loves it, he always says how great a monitor it is. Also, if you want to save $130, you can get Win8.1, the *cough*free way.
