Eric, What system do you have that produces the detail/quality level of the NorCal product on these screenshots? Would a 27" iMac be good enough to closely approximate what you show? Specs: 2.9GHz Intel quad-core i5, 8GB memory, NVIDIA GeForce GTX 660M with 512MB (would GeForce GTX 675MX 1GB be significantly better?). What upgrade will boost performance best? Thanks for your feedback! Manny
