So, i'm selling my 2 current systems to consolidate to a single mac system. I'm having trouble deciding between a nice macbook pro (high 15" or 17") or a 27" imac. here is the system i'm coming from that ran windows 7. Intel i7 920 cpu @ 3.5ghz 12gb ddr3 1333mhz ram nvidia gtx275 video card 2x150gb velociraptor in raid0 (10k rpm) 2x 640gb wd black drives in raid0 (7200 rpm) lacie firewire 800 pci card dell 24" 1920x1200 2408wfp lcd I would like to keep the price around $2,000 for the new system. I would love the portability of the mbp, but the 27" imac display is SOO nice and so is the faster processor. I'll mainly be using this for A LOT of adobe lightroom and some photoshop. Also having it store a lot of media(tv shows, movies, etc) probably on a fast external harddrive. i'm not worried about an SSD on either system at the moment requirements are an i7 for sure, and at least 8gb of ram, though i would like more than that later on. either system will be ordered with 4gb and i would upgrade it later myself. suggestions?
