Best CPU/CPUs of all time?

Solution
Everything is debatable, we can only attest to what we have bought and overclocked ourselves.

For me:
Socket 1366 an i7 950 OC'd to 4.9GHz system is being rebuilt and have a 975 and x5675 to try
socket 1155 an i5 2500k at 5.4Ghz and i7 2600k at 5.2Ghz
Socket 1150 an i5 4670k at 4.0Ghz don't have the time and my 980 doesn't push enough to warrant seeing how fast it will go. right now running at stock speed.
In short

Any i7 will be the best for gaming. Lot doesn't matter, yes some lots are better then others but its still a lottery as to how well the chip will overclock. Within the good lots there are still back chips. Temps all depend on the chip lottery and cooling method.

Unless you narrow down your search by year or gen of cpu, I don't think anyone is going to spend the time to go all the way back to early 2000's late 1990's and figure out what chip was the best for each year.
 
The best CPU of all time is the newest i7, when you compare with CPUs available today. Perhaps there were better "value" CPUs in the past, but as time moves forward, technology progresses and things get better. New tech is better than old tech.
 
That's debatable. Few months ago, before skylake was released, the newest Intel cpu's were the couple of Broadwells. I'd not exactly call them better than the Devils Canyons. And AMD's newest tech, whether the FX or A-series APU's isn't exactly a bag of chips either. Just as it wasn't that great when brand new.
 


Yep, the 3770k is still a great chip!

My 2500k @ 4.5 GHz is still serving me well... I'll upgrade at some point, but the new chips have not really blown me away. Perhaps I will pull the trigger if Kaby Lake is impressive.

I wouldn't say they were a game changer, the first gens were game changers. The gen 2's just became easier to overclock.

running at an everyday speed on my 950 @ 4.6Ghz vs my 2500k @ 4.6Ghz you couldn't tell the difference in game on a pair of 580's OC'd to 1000Mhz

I still use my 950 now paired with 4 Evga 670 superclocked+ for office work.
 
Intel I7 2600K or 2700K Sandy Bridge CPU's were and are the best chips (mainstream) that were ever marketed to the public...! The IHS were soldered and better TIM used than the next gen Ivy Bridge 3770K which had to be delidded and better TIM used to approach the Sandy Bridge...
Also, they ran hotter due to Intel cheaping out on building IB. Furthermore, almost all the architecture went mainly into the graphics..., If you paid 350.00 - 375.00 for a CPU for Gaming and Media you were certain to invest in a GPU and not use the on board graphics... Anyway I have OC'd them to over 5MHz on air stable however, not wanting to ruin the longevity of the chip I could always get a solid OC of about 4.5 - 4.8MHz on the chips, still running 4 of them on 4 of my personal PC's and they are like the day I first built the PC...
In my opinion Intel's Sandy bridge CPU's were the BEST chip ever offered for the money, the list of why this SB architecture is - was the best CPU one could write a book on it! Moreover, as mentioned above the 2500K SB even though an i5 still ROCKED and was just as good at gaming as the 2600K & 2700K's however, I always spent the extra and went with the i7's for the best all around (media) being a biggie with me.
 
My personal experiences with the i5-4690K and the i7-4790K were very good. The i7 I got up to 5.0GHz stable but I did not run it 24/7. But that 4790K was an absolute beast. With stock clocks of 4.0GHz you couldn't go wrong. Also an honorable mention to the i5-3570K. That one I had running at 4.6GHz all day everyday. Older than that I would say the Q6600 and E8400. Those chips were legendary. Still have one of each sitting in a drawer somewhere...
