I am planning to build a new workstation to get into video editing. I've based much of my hardware decisions based off the article below. The one problem I have is spending more on a video card than my processor/mobo combined. Is this really necessary? I looked at the resolutions supported on this card and they are way higher than any monitor I will probably ever connect to it. Any suggestions as to what I should look for to enable editing of AVCHD video?
