I'm a long time PC user with a i7 2700K 16GB 256GB Samsung 840PRO desktop and it still feels slow. I shoot RAW and work with Canon's software which I really like and Photomatrix. Before my current setup I had a i5 2500 8GB 128GB crucial SSD. The speed difference is quite small. I'm a bit disappointed. I don't care about silly benchmarks. I was wondering if Mac OSX and a new iMAC would be faster and deal with large raw files better than windows. Has anyone gone from a High end PC to a MAC and seen a performance difference?
