So I had my heart set on a Mac Pro until the new iMac comes out with similar specs to what I was looking at for seemingly less money (esp since it includes the monitorr). I do a lot of print design work in Photoshop where my file sizes sometimes get up to 1GB or more in size (posters tend to get this large)...so I want something that can do the job. I know there are differences between the imac processors and the Mac Pro's Xeons...but not sure if the improvement is worth the price difference. Any advice I could get would be great. Thanks!
