The FX 6-Core, like most CPUs from AMD, delivers reasonably good server orientated multi threaded performance and consequently good processing thoughput at a reasonable price tag. Where the FX 6-Core lacks is in the area of single core performance which although not normally a major problem for server workloads, is always very relevant to desktop users. The overall performance of the FX 6-Core is comparable to Intel's five years younger Core i7-950. There are server orientated use cases where the FX 6-Core will excel thanks to its excellent overall throughput and in those instances the FX 6-Core represents good value for money. But typical desktop users will find far better value elsewhere. [Sep '13 CPUPro]

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]
