Hello all, I've been a PC user all my life, but I'm looking to invest in an Imac in about 2 weeks. I'm torn between two options, and I'm hoping you can help me out. I'm trying to decide between the 5K Retina, and regular 27" Imac. My budget is about $3100, so that's what's prohibiting from deciding. For that price, I could get a fully loaded regular. However, seeing as I create images for a living, the 5K would be a dream come true. To get into my price range, I had to downsize the RAM to 8gb, while keeping the 4.0 I7 and the AMD 4gb. My question, is getting the 5K with only 8gb of RAM worth it? Am I better off doing this, and upgrading the RAM later? I have some extremely large Photoshop documents, with sometimes 1000+ layers, and my PC just isn't cutting it anymore. I also do alot of detailed renders with C4D, Modo, and ZBrush. Anything that'll get my render time down, I'm all for. No animation btw, just stills. I'm not the most hardware-knowledgeable person, so speak dumb to me. Another concern is heat. I've never owned an all-in-one, and with potentially day long renders, I don't want anything to overheat, or god forbid, melt. I'm probably just way too paranoid, I know. Basically, being a visual artist, is the 5K worth it, and just invest in more ram later? Is RAM even going to help me PS and render at lightning speeds? Or is that more the processor/v-card? Thanks a ton for any info you can share with me !
