Reasons to buy the Intel Core2 Duo E8400
 | Much higher clock speed 3 GHz | | 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.
