Hi! I read a lot of threads about new iMac - how bad is 20"model etc. Know I'm choicing between 24" old and 24" new model. The old 24 model spec are: 2.16 Dual 2 Core 320Gb 2Gb RAM Ge Force 7300 128Mb If the new one I will take 2.4 320Gb 2Gb RAM ATI 7600 256Mb What is main main problem here is a sceen. My hobby is photography so I need good screen. It is importand that I can evaluate highlights, shadows, colors. Can anybody who also works with photos tell me how bad or good is new 24" iMac comapre to old one if he used it. Thanks!
