From the point of view of a consumer that typically uses a PC for surfing the web, checking email, listening to music and watching videos, I consider that the Haswell i3 processors currently represent the best value for money. The i3-4130 has a performance profile that is just 7% below the top nine group leader average yet it only costs half as much. Power users that play intensive 3d games or run video editing, graphics design or CAD packages will benefit from more than two cores and will do well to look elsewhere but for regular users overall responsiveness will remain largely unchanged regardless of how much more is spent on the CPU. (My new value pick is the G3420 which supersedes my recommendation of the i3-4130.) [Sep '13 CPUPro]

MORE DETAILS

The Core i7-4790 is the third upgrade to Intel's flagship quad core hyper-threaded CPU. This version, like its predecessor the i7-4771, gets a 100 MHz bump in stock frequency and additionally the i7-4790 also gets a 100 MHz turbo frequency bump. These improvements (~4%) are marginal and practically impossible to discern in day to day use. Looking at a benchmark comparison between the 4771 and 4790 verifies that there is little difference between the two CPUs. Although the i7-4790 isn't much of a step forward, it's still one of the best (locked) mainstream processors on the market. AMD hasn't been able to compete with Intel on single threaded performance for several years, consequently Intel have no need to push the envelope. Overclockers should wait for the 4790K which is rumoured to be released shortly. [May '14 CPUPro]
