I recently started doing image color balance processing at work. We have an aerial camera system made up of 5 Canon 1DSMarkIIs and everything is of course shot in RAW. I have been doing it on some very quickly aging hardware and convinced my boss to spring for a new workstation pretty soon. I will either be getting a Mac Pro or a Dell workstation(eww I know). As it is I deal with anywhere from 400-1000 (multiply that by 5 as I only deal with one camera's files at a time) raw files at a time through Bridge and then loaded into Camera Raw. There is a huge difference just between the single core 3.0ghz desktop at work and the dual core 2.0 ghz laptop I have sitting next to me right now (I don't use my MBP because I don't have a Mac copy of CS3 yet). So I assume a 4 or 8 core 2.8ghz system would be amazing. My big question is whether I would see a bigger performance improvement with the 8 core or 4 core system? And also whether it would be better to get the cheaper 4 core and get extra RAM or the other way around? My boss is going to want to keep this as cheap as possible so I am trying to squeeze as much out of the price as possible. And maybe get an 8800gt in it too.. haha.
