Im thinking to build my own desktop for hackintosh instead of iMac and Mac pro. I still don't know why Mac pro is so expansive tho. Anyway before I start I would like to hear the max spec of each parts such as RAM, CPU, GPU, and etc. I really think that I need to get more RAM space like 32 or 64. 16 is def not enough. Yesterday, my macbook pro stopped working because all applications used all RAM space especially Photoshop. That just happened within 10min. People kept telling me that 16 is good enough but I don't think so. I have a lot of medium format files and scanned film files so having larger space of RAM is necessary. CPU is not that expansive which is around $350 but are there any differences between Xeon version? I do both game and editing programs but I will focus on the program. AMD Radeon R480 is a newest GPU and it has a cheap price but great gpu. Im thinking to get two of these. Any thoughts?
