The Intel G3258 is the first budget Pentium processor to feature an unlocked multiplier. This enables a comfortable overclock to 4.3 GHz using just the stock heat sink and fan. At 4.3 GHz, in terms of single and dual core performance, the G3258 challenges a fully overclocked i7-4790K, the fastest CPU I have seen to date! These results are stunning considering that the G3258 is retailing for around one fifth as much as an i7-4790K. The G3258's Achilles heel is its poor multi-core performance which is over 50% weaker than the group leaders. For the vast majority of users, assuming an overclock of 4.3 GHz, the G3258 is the best value processor on the market by miles. On the other hand, users that encode multi-media or run SLI/Crossfire setups should look elsewhere. [Jul '14 CPUPro]

The Intel Core i7-4790K, codenamed Devil's Canyon, is an upgraded 4770K, Intel's current flagship i7. The 4790K features an improved thermal interface which enables it to dissipate heat more efficiently than the 4770K. Comparing the 4770K and 4790K shows that stock performance has improved by 13% which is consistent with the base clock jump from 3.5 GHz to 4.0 GHz. OC performance remains unchanged. Comparing the 4790K and 4790 shows that at stock clocks the 4790K is around 16% faster which considering the small price difference makes the 4790K a far better choice. Previously Intel targeted the unlocked K versions at overclockers but with Devil's Canyon they have included VT-d on the K chip and this time it's squarely aimed at both power users and overclockers alike. Until the release of Broadwell in six months, the 4790K is the high end CPU of choice. [Jul '14 CPUPro]
