Here´s my thoughts: MB 4,1 basic 2,66GHz, do the 5,1 hack, upgrade to Hex CPU, 24GB RAM (1333MHz) and a decent GPU. SSD RAID 0 - either the Tempo Pro card or Accelsior E2 MB 4,1 Dual CPU 2,26GHz, no CPU upgrade, otherwise as above. MB 5,1 basic 2,8GHz, same upgrade as 4,1 unless the fw-hack. Either machine will be with dual monitor set-up Please keep in mind I live en Denmark, hence the prices nearly touches the sky. The 4,1 basic is way cheaper than the two other mentioned. Transformed to USD the basic will cost me around 1.000, where the others add´s another 5-700 My MBA suits me well, but do seriously needs power in PhotoShop and Lightroom. i´m aware a MM probably will suit my needs, but I like the possibilities in the MP. What do you think?
