This has been my daily driver since May of 2016, still going strong with some tweaks and updates along the way. I wanted to post this because I saw a couple recent videos about how the 6600k is obsolete because of the Ryzen 5's 6 cores and faster clocks in this class. While I agree for new builds and that the Ryzen 5 is a great piece and competitively priced, the 6600k is still a relevant and fantastic chip. This is the first PC I built myself, and I am proud that it continues to perform with some updates and OCs.
The original build had a ASUS STRIX GTX960 4GB card, no NVME, and stock fans on the AIO cooler. Upgrades I have made:
-September 2019: mild overclock on my GTX 960, don't remember the settings. Helped a bit to keep up with more demanding settings.
-January 2019: Bought ASUS CERBERUS 1070 ti, and the Dell S2417DG to go along with it. I never knew how great 1440p and 144hz was until I tried it. Gsync is the icing on the cake there. Looking at a 60hz panel just hurts now!
-December 2019: New peripherals, upgraded aging Logitech keyboard and G502 to Corsair K55 and Nightsword. Installed SN750 NVME as new boot/primary drive, and upgraded AIO fans to ML140s to support better OC temps while quieter.
-January 2020: Overclocked 6600k (finally) to 4.4ghz. I could have pushed it with more voltage, but temps were getting high and my case is a bit small, so air flow isn't ideal for a super hot OC, and I didn't need a lot. CPU runs 63ish under high loads with prime95, but only 40-43 while gaming. The 1070 ti manages a +165 core offset (~2025mhz) with a slight voltage bump, and a +450 memory offset (4455mhz on MSI AB, 8910mhz effective clock). The memory alone OC netted my about 7-10 FPS on high demand games, which is impressive, and the CPU OC helped minimize the slight bottleneck.
The recent additions of the NVME boot drive and overclocks have really helped my system's performance and stay relevant with today's games. I play a lot of Destiny 2, Civ VI, Battletech, Mechwarrior and Elder Scrolls, and these updates keep me at max settings with 80-100+ FPS on most games in the most demanding times, some far higher and most close to 144hz.
As you can see, the system is still relevant and very good for even 1440p gaming, 4 years after I built it with a now-5-year-old CPU. The Skylake generation was a resilient and reliable CPU set, and I honestly see no reason for a new build/upgrade unless I want to start streaming, use 4k resolutions, or ray-tracing becomes standard for future titles. Hope yall enjoyed my walkthrough, and I hope everyone else with similar builds can use overclocks and updates to their advantage and keep their rig's performing in the era of RTX cards, 8 core Ryzen 7s and RGB.
