Am an event photographer, currently using a mid-2010 21" iMac, 3.06GHz Intel Core i3 processor, with 6GB of memory on OSX 10.8.5. I use it to process literally thousands of images on-site during an event. By 'processing', I mean importing and 'making a copy' from the CF card to the desktop via Lightroom. These are then categorised and uploaded to a local-network website via Lightroom's web upload facility, with very little actual editing, if any at all. My issue is speed - I desperately need to speed up the importing and uploading process as it's currently costing me time and, consequently, money. Clearly a fully-specked Mac Pro would do the job, but my budget is more in the region of £750 to £1250 rather than £2500 upwards!! Maybe a new MacBook Pro (plus a cheap monitor?)? If so which one? Or a newer iMac boosted with more memory? Any advice would be very much appreciated.
