Late May, 2019: I ran into a problem for the first time ever with my Intel Core i7-950: it lacked the processing power to simultaneously encode and stream video content in 1080 resolution. I had been running that thing for years & years & had never even bothered to overclock it (wasn't necessary). With an Asus X58 Sabertooth motherboard, I could have overclocked that CPU, but instead, I checked for alternatives. Early June, 2019: I did some research & found that my motherboard would run a Xeon W3680 CPU, and that they easily and thoroughly overclock while running cool, and that they have unlocked multipliers, so I could leave my RAM & the rest of my motherboard running at stock speeds if I wanted to, etc. I bought one on eBay for an astonishing $40 ! (When this model CPU came out a little over 9 years ago, it was $999 !) I ran a test of the CPU at STOCK speed (133x25=3.33GHz). Cinebench R15 multi score: 825. I then left ALL VOLTAGES SET TO AUTO and changed ONLY the CPU's multiplier. Running @ 133x30 (4GHz instead of stock 3.33GHz), Cinebench R15 score rose to: 892. Running @ 133x34 (4.5GHz instead of stock 3.33GHz), R15 score made it to: 987. I have not even bothered to try to push it any further. This score beats those of *many* more modern, way more expensive CPU's running on newer sockets. This is proven faster than an i7-4770K that was overclocked to 4.4GHz ! Let me be clear: I was cooling this with a Hyper212 Evo, which is an AIR COOLER. Summary: I just spent $40 to bump up the performance of my Socket 1366 based PC to above the performance of most CPU's of the NEXT socket that came after it. I changed NOTHING but the CPU. Astonishingly fast, amazingly cheap. What's not to love about this ?Read full review

Great overclocker. This is the last great x58 cpu. 4.5ghz stable on air. Still relevant for many workloads in 2021.

Inexpensive 6-core upgrade for a 2010 or 2012 Mac Pro. Unlike the W3670, the W3680 allows the Mac Pro to run RAM at 1333MHz instead of just 1066MHz.

I'm really enjoying this new 6 core CPU. It is much faster than the 4 core I7-920, and it runs much cooler.

Arrived fast and super easy install. Works perfect.
