A dual-core is indeed what you want. Perfect time to purchase one too in
that Intel's new Core2Duo release has the prices on all CPU's plummeting.
While AMD has stopped production on their socket 939 and AM2 processors with
2MB of L2 cache (1MB/core) - they are widely available online with the many
resellers. Here's a link to the best buy I could find on the CPU you want -
the x2 4800+:
AMD Athlon 64 X2 4800+

For your application (video editing) - the 1MB of L2 cache/core is
beneficial. AMD has stopped production of these CPU's to help them cut
their production costs/CPU. Most real-world apps don't suffer from the loss
of cache memory with AMD because of their efficient memory controllers, but
your application does indeed benefit from higher L2 cache. Lucky you! The
online retailers are looking to flush out these chips from their inventory
and have slashed prices. In February '06 this CPU was $850 at NewEGG.
Socket 939 is a mature/reliable platform and will serve you well over the
next 24 months as the industry prepares for quad-cores and AMD moves to a
65nm production process. With Socket 939, you won't need to upgrade your
mobo and buy DDR2 memory either.
Here's a recommemndation for your video box:
