Based on 15,144 user benchmarks.  Devices: 178BFBFF00100F43, 178BFBFF00100F42 Model: AMD Phenom(tm) II X4 955 Processor

The AMD Phenom II X4 955 is a quad-core processor based on the K10 micro-architecture. When it launched in Q2 of 2009, it was AMD’s fastest CPU. Given its base clock of 3.2 GHz, with appropriate cooling, this unlocked Black Edition chip can be overclocked to speeds in excess of 4 GHz. The 955’s effective speed of 63 isn’t impressive by today’s standards, but when coupled with a decent graphics card, it won't cause major bottlenecks for most games. The 955 was pitched against the high-end of Intel’s Core 2 quads, and now costs a fraction of its original list price as one would expect, however there are better alternatives on the market now. [Dec '14 CPUPro]

i use it even now(in the end of 2017) and still work verry good, but because is age(9 years) latest games only work on minimum(at least they WORK)

low perfomance for that price

Very good

Very good for it's age. And even if it's a 3.2 GHz CPU, it's easily overclockable to 3.7 GHz without changing the voltage. (Still there are lots of better choices today, so don't buy it. Go for the fx line if you want more power for less price in the AM3 socket erea. But if you are open then go for Ryzen or the 5-7 gen intel CPU-s.)

Very good

old school design, but can OC over 4Ghz (mine is sitting on 4.1Ghz and has been for near 3 years straight). outstanding bang for buck!
