Received my new 24" iMac on Friday and have been using it over the weekend. I've got to tell you I'm really really impressed with the performance. I use adobes CS1 at home running previously on a 1GHz eMac, and I use CS3 at work on an original 2.0Ghz intel dual core. Now we had CS2 at work before we got the new CS3 suite, and while faster then CS1 on my eMac it wasn't much better.CS3 transformed things on the 2.0Ghz iMac as is really speedy.So I wasn't expecting much from CS1 on my new iMac. Well imagine my surprise CS1 runs like a rocket, on the 2.8GHz processor, everything opens up like lightening and manipulating images is fast.CS3 is still a bit faster (i used the trial versions) but the difference is no where near as much as it was the 2.0GHz, where CS3 is almost essential. Although I must point out CS3 is faster on the 2.8 then on the 2.0 in case I'm confusing you. I'm well cuffed as it means I can keep using CS1 and spend my money elsewhere.
