2.66GHz is only worth it if you do a lot converting or export&importing, especially if it's work related. Wasn't a surprise for me... It's only 260MHz and +1MB cache in i5
 
Well only reason I was originally going to go with it was for the 512mb of Vram but then after seeing how closely those numbers were I am so happy I went with the base i5 :)
