Hi doveman
For video encoding it might be more desirable to have a quad core. It is a trade-off though - if you want low power and cheaper then it seems like an okay option. In the past people have had problems viewing 1080i in MP with the HD3200 (just not powerful enough). Don't know if that is still an issue.

Bit late there CrashUK I ended up building with an Athlon II X4 630.
