When it comes down to it is the performance leap huge enough for me to build an i7 system over an amd system. I prefer amd abecause of the competive pricing. The amd flagship entusiast level CPU is under $200 and intel's flagship entusiast level CPU is $1000 dollars. when I say performance leap I mean an absolute revolution like the jump from intel 486's to pentium ii type performance jump. I dhaven't had experience with either cpu so I wouldn't know. I want to know if that's the case or not. All I do is game and video edit. From I what I have gathered AMD likes video editing a little morethan intel chipsets but the i7 is in a different league than past intel sets so they claim so basically someone please guide to this big difference ecause I just don't see why to spend and extra 800 bucks that desperatley need for something else and have trouble scraping up 500 for a system build at all thanks to the wonderful economy. so someone please educate me why it is sensible to pay 800 more dollars for a multiplier unlocked i7 over a phenom ii 965, please explain to me what this big difference is that everyone keeps talking about.
