LOL...this is a great site, but it's not the only source of valuable information about the various aspects of computing.
I based my response on the steps that I took before I decided to buy my first capture card and delve into video editing. I read a lot, visited the Adobe forums (even though I have never/will never use Adobe graphics/video software) and then decided what my hardware requirements might be to achieve my end purpose.
It's not like just going out to buy a camera (which is complicated enough) and it saves a lot of potential frustration, IMO, if I can learn from the mistakes, dislikes, likes, etc. of others who are attempting/doing that which I aspire to.
After all was said & done, I came to the conclusion that any system will allow video editing...the variable was how fast the editing took place and the quality/quirks of the software I would use.
The software is important because it is what actually does the work, enabling the rendering of video. Along with the software, I find that the maximum amount of RAM (2-4GB) is a big factor.
With multicore processors today...it just seems logical to me to build on the experiences of others...before I commit myself to any particular hardware and/or software.
Well-intentioned persons will provide opinions about many things on the Web, not all of them are accurate or free from personal bias. That bias is ameliorated somewhat when one gathers a wide, diverse array of opinions...before deciding to spend cash for anything, IMO.
I will also mention that there is a fair amount of data out there regarding rendering times/differentials for various processors when it comes to video editing.
FWIW: A video card is important for gamers...it's not important at all for video-editing. RAM is the most important hardware item, IMO. Any multicore processor...is bound to yield faster results...than a non-multicore...but it won't process any better. You decide if the speed differential is important.

Almost forgot...you don't seem to include RAM in your list of components you have decide upon.
