So I've been busy over the past year. I still have my 860K, and it's currently overclocked to 4.3GHz stable. I'm cooling it with a Cooler Master Hyper T2. Does the job pretty well.
Over Christmas, some family got me an extra kit of RAM, the ASRock motherboard, and the ADATA SSD. I have all of these in the build now, and it's kicking ***.
As you can see, I have a Gigabyte GeForce GTX 780 as my GPU now, over the 950 I originally started with. (Don't worry, I made up my money on the 950). The 780 is the GHz Edition. Kickass card.
All in all, this build is now perfect, in my opinion. I couldn't be happier. It kicks *** and I haven't had issues with it yet.
