What's a good LGA 775 gaming CPU for under $200?

Hi. My current CPU isn't cutting it, so I need suggestions for a new one. It is an Intel Core 2 Duo E6300 with 1.86 GHz. The kind of games I'll be playing are things like Battlefield 3, Red Orchestra 2, Wargame: EE, and the like, so I'd like one that can run those, preferable for under $200. It'd also be nice if you could provide a link to the CPU you suggest. Any help is appreciated!
