(I'm hoping this is the right forum for posting, apologies if not. Presently working my way through the iMac thread). Hello Mac Forums. I'm hoping to purchase a new iMac or PC soon and seeking some advice. I'm working on an ancient MacBook Pro (2006) that is wheezing along. I'm an artist that uses Creative Suite (working on an old version of CS4 now) and hope to begin incorporating some GIS and basic CAD drawing into my work. I do not plan on doing really complicated rendering with GIS, just want something that will not overheat when I get a few programs going. I prefer Apple's operating system, design, and overall functionality. I've been looking at new iMacs, refurbished iMacs, and used iMacs on Craigslist. A friends who works with similar software had PC put together at the local Micro Center for significantly less. Budget is an issue, but I also anticipate keeping this computer for a while, so over the course of a few years, a few extra hundred bucks is not huge. Any thoughts on PC vs. iMac, refurb vs. new, how much power I really need, or anyone that is working with similar graphics heavy software that has an opinion. I try to read the technical specs and forums, but at some point, it really is a foreign language. Any advice would be greatly appreciated. THank you.
