It appears that I'm caught between a rock and a hard place. Right now, I'm looking at these 3 computers here. I'm shooting with the BMCC in CinemaDNG and I need a computer that can handle it with as little hassle as possible for around $2,000 and 2,300 . I'm also platform (MacOS, Windows 7/8) agnostic.
I'm biased towards the 21.5" iMac because of the color accurate display, though, the dell is a close second. The 27" iMac looks awesome, and would allow me to expand to 32 GiB of RAM, however, it's featuring a 7200 rpm HDD, and I don't feel like opening it up because of warranty conflicts. The Dell would work after I got a colorometer for it, features 32 GiB max and has a Quadro K3000M. Which should I choose?
