Reasons to buy the Intel Core2 Duo E8400
 | Much higher clock speed 3 GHz | | Much higher Maximum operating temperature 72.4 °C |
| | Supports trusted computing Yes |
by Anthony-Garreffa (Sep, 2012)Your GPU setup is more than good enough to run Battlefield 3 at medium-to-high settings at 1920x1080, so I would suggest waiting and upgrading to an Ivy Bridge setup.

by Tech Radar (Feb, 2007)However, it's during overclocking that this chip comes alive, hitting 3GHz, and not only cranking out performance numbers that would have been utterly unbelievable for a budget chip a year ago, but also coming painfully close to matching the likes of the premium-priced Core 2 Extreme X6800.
