3. Intel 3.2GHz Core i5-3470
Here's further proof that Intel's Ivy Bridge architecture for the third-generation Core series is still the gold standard (and there's more to come). Released nearly two years ago, Intel's quad-core 3.2GHz Core i5-3470 chip features a Turbo Boost speed of 3.6GHz plus 6 MB of Intel Smart Cache. The chip also comes with Intel HD Graphics 2500. While there's no unlocked multiplier for overclocking, the Core i5-3470 is still a workhorse processor with an affordable price tag of $195.
