I7 2700k bottleneck?

My secondary system is still rocking a 2700k @4.8ghz on air. (it can hit 5ghz but causes weirdness in windows)
Paired with OC FuryX.

No bottlenecks

Sandybridge (when OC'd) is still a very compelling chip (assuming it's cheap to pick one up with a board). The only downside is the lack of features modern day systems have now like PCIe NVME SSD, Type-c TB, etc

Even Luke's personal rig is still running a 2700k iirc.

yep, i have my 2600k at 4.7ghz, and can run stable at 4.8Ghz. I just don't know how much longer its going to be before i upgrade, so i don't want to push it too hard when i don't have to.
