Well..... theres not a lot of difference, so i guess not I'd only buy it if your really in ps, and are thinking of becoming a GFX designer but thats my opinion...
Juz got Cs2.. Cant realli see much difference.. The only thing that is good was the Text Sample.. It helps alot in choosing text//
i have all 3. period. to be honest, i the only reason why i keep updating is because brushes out there keep coming out for the most recent version which is retarted. and it's harder to find it on photoshop 7. feature-wise, i think either photoshop 6 or 7 was the best.
keep wat u got i have cs2 and i love it but i dont care wat photoshop i got has long has it is over 6.0
If you get an upgrade get CS, not CS2... Older versions are cheaper, and cs2 is more for photoediting
i personally found CS2 slower then CS, but really.. 7.0 is good for pretty much everything (although some brushes are for CS +)... i do like the text preview in CS2 though as someone else said..
