Option B: The High-Clocked Dual-Core Upgrade (Intel Core 2 Duo E8400 or E8600)

The Intel Pentium Dual-Core E2160 was a legendary budget processor released in 2007. Built on the Conroe-1M architecture using a 65nm process, this chip clocked in at 1.80 GHz with a 800 MHz Front Side Bus (FSB) and 1MB of L2 cache. While it was a champion of the budget overclocking era, modern operating systems and web browsers easily overwhelm it today.
