Hello. I'm wondering if getting the Dual Core Athlon 4200 is worth getting, whilst it's on offer, or the (none dual core) Athlon 64 4000, for a video editing PC? I was told that the 1mb cache, that the single core Athlon has, is better for video editing. The dual core has only 512 kb cache. I've also got the same question for another PC i'm building for a friend, but his PC is for video games. Is there much difference in speed, or is the advantage of Dual Core only the ability to run more programs at once? I don't imagine either PC will run many programs at once.
