5.8 Out of 10
Reasons to buy the Intel Core2 Duo E8400
 | 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.

Intel Core i3 3220
- 3.3 GHz
- Dual core
7.3 Out of 10
Reasons to buy the Core i3 3220
| | Much higher clock speed 3.3 GHz | | Much newer manufacturing process 22 nm |
| | Has a built-in GPU Yes | | More threads 4 |
by Don-Woligroski (Oct, 2012)The Core i3-3220 doesn't benefit from Intel's Turbo Boost technology at all, but instead relies on an architecture able to execute more instructions per cycle than AMD.
