Hi all, Just checked out the 5k in the Apple store today - very clear difference in the screen. Not sure I need that compared to my ViewSonic 27", but I want to replace my 2009 Mac Pro. Here is the config I'm thinking: 4.0GHz CPU 295x GPU 8GB RAM (upgrading to 24 after the fact) 512 SSD (most of my data will be stored on separate USB3 SSD drives) I mainly do music production and photography on my machine. What do you all think? Is the 512 SSD worth it over the 1TB fusion? Should I get regular iMac instead (though similarly spec'd only is $400 cheaper)? Or maybe a maxed out rMBP (cheaper than the 5k by $500). Cheers!
