Having used laptops since moving to Aus (portability over performance), I needed to finally build a home PC for gaming, media and general Photoshop work. I wanted something fast in every day tasks but also a beast when it comes to gaming specifically. I don't often render many videos or require 8+ threads and extreme amounts of RAM - my laptop has a 4700MQ and 16GB of RAM so if I ever needed it I could use that. Having a max $3000 budget (more like $2500 for the chassis alone) I starting putting together parts about 12 months ago. Originally I went for an i7 and a 770 then 970 combo but decided on the unlocked i5 and a 980 - making sure I have the graphical grunt but still have a decent CPU which the 4690k is (it also overclocks nicely). It means my future upgrade plan would consist of an i7 and another 980/a greater performing single card.
I began purchasing parts at the end of 2014 and got them all by early Feb 2015. Built took about 4 hours (it's been about 6 years since my last) which wasn't bad, it fired up first time too!
I upgraded all of the fans on 21/03/15 - with 2 Noctua and 3 Corsair fans to add some lighting and better airflow through the case. I've played with clock speeds - my i5 sits at 4.4GHz at 1.150v with Intel tuning utility getting it to 69C max, gaming (BF4, Crysis 3) is more like low to mid 60's depending on the core. I'm using Arctic Cooling MX-4. I left my 980 with the standard EVGA overclocks - I do plan to put it through its paces once it starts to struggle with anything - gave it a mild overclock, seeing as it isn't effecting the temps :)
I'm pretty happy overall. The Phanteks Enthoo Pro was an amazing case to build in - so much room, good airflow, well put together (crap plastic panels however!). The Asus z97-a was great too with well placed fan headers, nice adapters for case switches etc and plenty of ports for all my drives and has a great bios. I'm also really pleased with the Asus wireless card - epic performance!! The Corsair H60 SE is average, it suits my needs but I will definitely consider something more robust if I move to an i7 - I do prefer it over an air cooler as I can see my parts more easily.
