Can anyone suggest components?

[mysteryman]

I am going to build my first pc. Now i do a lot of video editing etc. I rarely play games although the possibility of playing latest games would be nice as well.
I want at least:
2gb ram
decent graphics card capable of handling some current games
CPU, preferably dual core can't decide on intel or AMD?
Motherboard?

I want to be able to overclock as well so if anyone can suggest what parts would be good value for money?

My budget is £500-£600.

Do you need all parts or just CPU, motherboard, Ram and graphics card? It is difficult to get all components for around £600 but this is about my best shot.
