Help need in upgrading CPU

Hi,
Can someone help me in upgrading my PC.
The existing configuration is Intel core i5 2.8Ghz (bought before 8 years) + Intel desktop boards DH55TC + 6 GB DDR3 RAM + 1gb DDR3 graphic card.
As I am planning to use some video editing softwares. I am planning to upgrade My PC.
Could you please suggest some budget processors and motherboards which an serve this purpose and a motherboard which will be able to accommodate the RAM/ graphic card and DVD drives from my existing PC.

Is AMD FX4300 good enough for this purpose?
If this is good, please suggest a motherboard for this processor.

Regards,
Naveen
