core 2 6400 vs amd 64 x2 4200

[hoopking]

Ive been looking at computers for a few months. I was about to pull the trigger when the new core 2s came out. The computer will be used for poker, video editing, auto cad, and possibly gaming. My questions are: When will we see price drops in the 4200 systems? The chip prices were cut by $130 a couple weeks ago, but the price of built systems(HP, Gateway, etc.) have not come down in the last several weeks. AND With a core 2 6400 system only about 300 less than the amd 4200, will it be worth the money to go with the new technology? I plan to keep this computer for at least 5 years.
