Hi I heard about the new AMD M2 Socket and its DDR2 capability and thought that I might build an AMD PC that is good for video editing and Gaming. I will mainly use the pc for those 2 things and I wanted to get sum ideas on what would be best to build a budget AMD PC that can do those 2 things better than a P4 3.0ghz Socket 478 pc which i currently have now. I will mainly be encoding in xvid and divx formats. So if anyone has any suggestions on what would be good for my pc then please tell me. I also dont wanna go over $1500 I am thinking of gettin these components aswell.
