I currently have a PC. (Yes, I'm sorry.) I'm needing to do some pretty delicate editing and color adjustment work with large Photoshop files, about 675 MB. The color needs to be really good - maybe not 100% accurate, but 98.5% good, if you know what I mean. The artist, my mother, is picky and computer illiterate, so the job is mine... Here is the problem: Our budget would now possibly cover a 1.25 single G4, but not a G5. My question is this: Just how important is a Mac to be able to get really good color? Is the colorsync or whatever in a Mac that much better? And if Macs are that essential, then why do I hear of some graphic designers using Wintels? Are they just sticking to what is familiar, or have they gotten PCs to really work for them? Is really good color even possible on a PC? Do you think I should get a Mac - even the 1.25 single G4 - or put the money into upgrading my PC, a 1.8 Pentium 4? I don't yet have the full Photoshop so I need to know what version to buy, Mac or PC. Also, if I do get a single 1.25 G4 with an extra 1GB of RAM, do you think it could handle a 675 MB Photoshop file? I tried the file on my 1.8 Ghz Pentium 4 with 512 MB and it was slooooooow. Will a single-proc G4, even with 1.5 GB RAM, handle such a file? Thank you so much!
