http://www.barefeats.com/imp03.html shows the 2600 beating the 8800 by a LARGE margin for iMovie and iDVD, both consumer-level apps that one would think would be more processor intensive. I just ordered a 2.8 iMac with the 8800 thinking it would be a better all-around graphics card. It looks like it is significantly slower for every-day apps. Anyone know why? Since this is a BTO I won't be able to return it easily and am pretty disappointed.
