yea i am new when it comes to this but the model of computer i built was much cheaper then any hp model that had half the stuff this custom PC has. This PC came out to $1450. And vegas 10 does use a 64 bit program.
All in all im just looking for a solid computer and editing software that will be relevant as technology changes.
(BTW are the HP computers your talking about the z400-800’s, cause i am still browsing what will be the best choice.)
