Yeah, I still have a 2500k at 4.6 with no over-volting on air. I wish I had an m2 SSD, but with the GTX1080 and a new 4K IPS TV which also does 120hz at 1080p (Vizio p55-c1, but read the rtings.com review about the lack of true 4:4:4 chroma if you're considering this one), it's been great for 4K and fast action gaming at high frame rates. Has no problem holding 120fps at 1080 with max settings in Overwatch, though I tone some effects down to make it less distracting and easier to spot baddies.
It's crazy to me that this old CPU is still all I need, but the ROI from an upgrade just wasn't worth it. Going from 2X Radeon 6870 to the GTX1080 was a huge performance boost, though, and I'll never deal with multi-GPU again if I can avoid it.
