I can't decide between the two How much more powerful is the mac pro to the MBP? MBP Cheapest 2.4ghz 4GB Ram Upgraded HD to Seagate (or WD) 7,200rpm 16mb cache 1 USB external disk for time machine 1 FireWire external for 'extra' storage space (All important files such as OS, my files and emails etc on internal HD) Mac Pro Cheapest 2.66 quad Nehalem 250gb 7200 16mb cache HD for OS 2 x 500GB 7200 16mb cache HDs in Raid 1 (mirror) for all my files Speed is important to me as I'm coming from a very past PC, I'll be using the computer for photoshop, coding and general pc stuff, I do however have up to 50 tabs open in my browser when surfing (and I surf often). I have the MBP right now but can still return it if I want to, it was feeling a little slugish when browsing until I bought an airport extreme base station and now it feels a lot snappier (which is what I was used to). I was going to set the MBP as follows, internal HD for all important stuff such as emails, files etc along with one external USB drive for time machine (to back up internal drive) and another USB or firewire drive for unimportant stuff, such as high definition trailers, images from camera and other downloads (and I'd move the one's I want to keep to main HD). However usb drives are capped at 480mbs and even firewire at 800mbs wouldn't be as fast as a proper internal HD. The Mac Pro would be set up as follows, internal HD1 (250gb 7,200) for OS only, and two 500GB 7200 disks in Raid1 for a mirror of each other where all my files, emails etc will go - so I have an instant back up of all my important stuff. I would rarely need the portability aspect of the MBP (and have another laptop if I really needed that). I do however like how quiet it is The expandability side of the Mac Pro does appeal to me as at some point I may be interested in getting a HDMI card to rip video footage from a compliant device (not 100% yet but it's something I'm thinking about). I don't game on my PC and have no intention of doing so (got a PS3 for that!) So what do you think if the cost between them doesn't really matter? Are there any other pros in getting a Mac Pro?
