I wanna get that CPU, but i enjoy the i7's more. I like to have an i7 over i5 lol. Personally.. However, more Ram? I do plan on getting more after I buy it. I think 8 should be okay for now. Also, I dont plan on overclocking, should I still get a better cpu cooler?
i7 4790k will be perfect for what you want to do with the PC. Personally I alway buy the K editions because there is only a small price difference, you get a better return on a K edition if you ever wanted to sell it and there is always to option to overlock if in the future you decided you need a little bit more power.
8GB of RAM will be more than plenty, there is a good chance you will never hit 8GB unless you are playing with massive photoshop files etc.
The cooler is a great cooler for the price and you can get 2x4GB RAM in dual channel mode then upgrade to 2x8GB later. RAM seems to hold its value very well so you can easily recoup the money back from the 2x4GB to pay for the 2x8GB.
Slightly tweaked it to my liking. http://pcpartpicker.com/p/swJ7dC
Don't step down from your 4790k, It might run you a little more now, but we're talking about a PC that'll last you 3 to 4 years.
EDIT: and if you want to save a little more money, Amazon is selling SeaSonic SS-850KM3 power supplies for $100. They are brand new OEM bulk repackaged power supplies and are listed under the "used tab." BUT I purchased one and I can assure you that they are brand new, plus it's sold by the Amazon warehouse so you know they wont lie. 850w, 80+ gold, fully modular, silent fan mode switch, etc.
