I'm sick of waiting for new iMac this year. So, when ever new one would be released, this summer, this fall, 2012... I don't care anymore. I need to buy an iMac 27" 2011 tomorrow and really need your suggestions. Assuming that I will use this Mac 15 hours every day: - Photoshop with 3-5 large files opening (20-30MB and hundreds of layers) - Firefox 20 tabs (Flash, JS, large pictures...) - Chrome 10 tabs - Some small office softwares - Dell U2312HM External Monitor Do you think an iMac with this configuration is enough for the tasks: - i5 2.7GHz - 12 GB RAM (I will upgrade this later with an external 8GB RAM - $50) - AMD Radeon HD 6770M with 512MB - 1 TB HDD - 120GB SSD (I will upgrade this later) Any suggestion or comment would be much appreciated. Thank you.
