I can't find benchmarks that compare the iMac vs Mac mini for compiling XCode project. I have interest in: 21.5-inch: 2.5GHz 2.5GHz Quad-Core Intel Core i5 vs 2.5GHz : 500GB 2.5GHz dual-core Intel Core i5 and upgrade any of them to 8GB RAM or more. I'm only concerned to have good performance to compiling with XCode. I *suspect* the diference between the two are not big, so my first inclination is the mini (I prefer a mate display, and the posibility to add SSD later look easier in the mini), but and the end development is what matter for me. Any benchmarks for this case?
