I just ordered a single quad 2.8 with wi-fi and 8800 video card. I can wait an extra x number of minutes/hours for video rendering as time is not money for me. Until common apps are eventually written for all 8 cores, I can't see spending an extra $500 + tax on something I personally may never need. I only use FCE, iMovie, and Garage Band. As for the upgraded video card, I did game in the past and if I start again I'll be prepared. Also the consensus is that in the future more graphic processes will be delegated to the video card instead of the core processor. The 3-5 weeks wait is irrelevant to me as I've already been waiting since last summer. So I guess I just ordered a new Mac "mid-tower". I can hardly wait to put this Powermac G4 D/A out to pasture. It's days of video editing (slow,slow,slow) will be over in 3-5 weeks. Bring on Leopard and the new FCE!
Just cancelled this order and re-ordered dual quad 2.8 along with wi-fi and 8800GT. I figured for the extra $500 now I'd guarantee all future apps will run as fast as possible and I wouldn't be sorry 2-3 years down the road. I plan on keeping this MP for at least 5 years.
