I just purchased a Mamiya 645 AFD11 with Leaf Aptus 22. I have a Power Mac G5 with 10.4.11 software and 3GB Ram. I cant seem to find a real good Software( like Capture 1 or LR3.5 ) that will work with my current( somewhat antiquated system). I am not sure if I should try to find a good software with my system or Buy A Newer computer that wont break the bank. I am now retired and just do some portrait work. Thank you
