Thanks 'Bear'
I will be mainly using it for Photoshop, Bridge, Portrait Professional, Lightroom and Microsoft Office. I usually import many Raw files into Bridge and process in Camera Raw as well as retouching images which often have several layers. I have a 2009 Mac Pro at the moment which is ok but can get bogged down a bit when saving large files and creating thumbnails in Bridge. I will also be running a second 23" ACD from it.
Many thanks
