Recently replaced laptop with Win 7 64bit 2.2 i7 Thinkpad W520 with 8GB of RAM and pretty high spec graphics card. I think that should be faster for Photoshop than my desktop, which is Vista 64/Intel6600 and about 2.5yrs old. I was wondering if I could use laptop as primary machine running its own screen and also my ACD 23" via display port-DVI link, so that images on one and toolbars/palettes on the other? Also, is there some way I could take advantage of the desktops internal HDDs (2x640GB in RAID 0) which is the one area it has an advantage over laptop's 500GB HDD?
