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]

The Intel Celeron G1840 is a budget dual-core processor for desktops. Released in Q2 of 2014, this Haswell based CPU is 10% faster than its Ivy Bridge Celeron predecessors such as the G1630. The G1840 is very similar to the Celeron G1850 and G1830 which were also launched in the first half of 2014, which begs the question from Intel: Why? With its base clock speed of 2.8 GHz, the G1840 scores an average effective speed of 73 which is ample for basic processing needs. The G1840 has a TDP of just 53 Watts, so it's a low power, low heat and therefore low cost processor. Coupled with an SSD and a decent graphics card the G1840 will give a pretty good user experience, but the 100 MHz faster and similarly priced G1850 is a better option. [Nov '14 CPUPro]
