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]

The Athlon II X4 750K is not about outright speed, it's about value for money. As a result of its relatively weak single core performance, which is around 26% slower than the 3225, the 750K scores in the bottom 34% for real world consumer performance. The Intel competitors offer far snappier response times but only if you are prepared to pay around 70% more. If you are on a super tight budget the 750K may well be the best option but for most consumer orientated tasks it's probably worth paying a little more. [Jun '13 CPUPro]
