Actually video editing and games make different demands on processors and
mainboards. For almost all of your computing needs I would recommend an AMD
Athlon 64 processor and one of the name brand boards with an Nforce chipset
like ASUS or Abit. For rendering video however, it seems the Intel Pentium
chips have the edge, so if video editing was going to be my main job, then I
would go Intel. If video was only going to be part of what I was doing,
then AMD is the way to go.
