It depends greatly on your needs. For gaming right now, the FX6100 and 3770 can handle anything. For video editing and stuff like that, a 3770 will be the better choice. The best cpu between those will be an i5-3570k/4670k or amd fx 8350. both are awesome and will serve excellent in gaming and multitasking. Thats the best choice, depending on your needs as i mentioned before and your budget.
