This is an upgrade to an old build here. Since then, there were some incremental upgrades. The main reason for the upgrade was for Battlefield 4 multiplayer. The old i5-3570k was able to keep up in almost all games, but when it comes to a high tick-rate server with 64 players in BF4, it would get crippled. I would be stuck at 98-99% CPU utilization at all times and GPU utilization on a GTX 980ti would be around 50%. This would cause huge framerate drops and stuttering in areas where there were a lot of people and where there was a lot of physics in play (i.e. things on fire, ashes floating). This meant that the multiplayer game was intensely CPU limited.
Because I play BF4 a lot, I wanted to upgrade to an i7. It was either a 5820k or a 6700k and I decided on the 6700k because of a higher clock rate and higher IPC. I read from forums and found anecdotes that even though a 6700k has two less cores, it was a better performer in BF4 because of the higher overclock potential and the higher IPC. I had read a 5820k doesn't overclock nearly as high and on average gets 4.0-4.2 GHz stable. The only other issue that made me hesitate on the 6700k was the price. It was $50 over retail while the 5820k was $320 at microcenter. Once microcenter dropped the price to $314 for pi day, I felt that the 6700k was the best performer for BF4 and for other games that might depend more on higher clock and higher IPC and don't use more than 4 cores/8 threads effectively.
Once everything was put together, I was able to test the performance of the 6700k in BF4 as compared to the old i5-3570k. So the end result is that I don't get a higher overall score in firestrike but I get a higher physics score which is important in BF4. Objectively, I am getting on average a similar FPS range on a 64 person, high tick-rate server, but subjectively, I get much smoother gameplay with no stuttering or frame-rate drops. It is a much better playing experience then the 3570k and I get 60% on all 8 threads and around 80-90% GPU utilization.
Over the past year, I also made some changes to the case. I gutted the lower and middle hard drive trays to increase airflow and then added a larger window and a PSU shroud so that I could use PSU cable extensions instead of expensive custom cables. Also added an NZXT LED light strip.
Overall, really happy with the build and how it turned out and it will probably be another few years before I upgrade the system.
Almost dead silent and looks good with any setup. I can barely hear this if at all over my case fans. It keeps a 6700k around 35C at idle and 60C at load.
After the issues with the Samsung 840 evo and the fake fixes, it lead me to try to avoid samsung even though the issue was fixed in the 850 evo. The bx100 is slower than an 850 evo but it is unnoticeable in real world scenarios. The drive is rock solid and still blazing fast.
I side-graded from two GTX 970s in SLI to this and it works much better than them. The overall firestrike score was higher for the GTX 970s in SLI, but because of the memory issue and general SLI issues, this one card overclocked gets almost the same firestrike score and is subjectively better in games because I don't get SLI stutter. The card is cool and quiet, looks great, and handles all games without problems.
This fully modular PSU is rock solid and provides clean power for overclocking quietly. It is highly reviewed with highest ratings on Johnny Guru and techpowerup. Haven't had any problems.
The monitor itself is probably one of the best out there. You cannot beat IPS 144hz and g-sync. The only reason the monitor can't be recommended is the QC issues. It had horrible QC issues that a $700 monitor shouldn't have. I got 2 dead pixels in the middle third which wasn't worth the hassle of the return but still annoying.
Solid construction with that awesome mechanical feel. Have had it for two years without issue.
