Review and comparisons between the 21.5” and 27” new iMacs:
MacWorld review of 27” iMacs with different hard drives:
Thanks Klaus but I should have been more specific
I am proposing to buy iMac 93/BA. For approx £150 more I can improve the processor by buying the 94/BA.

No idea as I don't use Aperture!

Let me know if you want me to ask the Hosts to move this thread to that forum.
