Hello all, I've been lurking here for the last few months trying to determine the answer to my question, but haven't really come to a decision so finally thought I'd throw out a few questions for some opinions! Usage: I am an amateur photographer but have lately been working myself into a bit of a niche that requires more computer than I currently have. I use Aperture 3 as my bread and butter editor/DAM and use PS for specific fixes. I am finding my current computer slow for this. However, I have been working towards multi-stitching landscapes, which requires stitching together upwards of 9-12 photos and pretty much grinds my current computer to a halt, both when stitching and when trying to edit them. Computer Choices: I have been looking at the iMac 27" with either the i5 or i7, and from a raw power perspective I think they are enough, but the screen very much concerns me (yellow tint etc). I'm still working on a 20" iMac with a matte screen and don't relish the thought of a glossy one either. Mac Pro would be nice from an expandability point of view, but I don't know that I would really push its limits in terms of raw power. I would also be able to choose a proper display, something like the NEC 2690 (http://www.necdisplay.com/Products/Product/?product=e46df7f2-40d7-4b16-b6ed-9c444e398f11). Biggest draw-back here is price. I am budget constrained to around 3k, so I would either be stuck with a smaller monitor or a much older refurb/second hand MP. 3rd option is a hackintosh I guess - after reading Cindori's thread they seem viable, but I don't want to spend a month building it either. I have built a computer in the distant past (Win 98 days), so could probably manage it again, but haven't kept current so would need a parts list I think. (And from an artistic engineer's point of view I do really appreciate Apple's product design!) Current computer for comparison: iMac 20" 2ghz Core Duo (NOT C2D), 2 gb ram, and the (accursed) ATI x1600 (which is giving me terrible graphic glitches in SL).
