I am a graphic designer. At work I have been asked to spec new workstations for our design dept, they have to be IBM Compatible (aka not macs).
Currently: 2.80 ghz C2D 3GB Ram 8400 GS gforce Barracuda 7200 500gb (space isn't an issue since stuff is saved over the network).
I'm out of the loop on vid cards and we have to stay on Windows XP. I don't think we can go NUTZ with the hardware request but id like to recommend a really hardy Bang For The Buck upgrade for hardware regarding our usage of the adobe suite.
Also my boss uses a laptop, company issue is a lenovo thinkpad and it's very troublesome and slow, so a portable recommendation for a creative director would be good too, again windows only.
