I am close to buy a new workstation (PC based, maybe Dell Precision) and thinking about upgrading Studio 8 to Creative Suite 3 Web Premium. The price difference between full version and upgrade is $1,100 which is hard to ignore.
- how useful you found your move from Studio 8 to CS3? - if you upgraded, did you have any problems with upgrade? My understanding is that upgrade requires you to install it onto same platform, no fresh install, I hate new over old. - Vista 32 or 64 bit? Pros and Cons? I know CS3 is 32-bit, but 64-bit OS should still be a benefit on single Quad Xeon with 4GB of RAM.
I can't answer your exact questions but I can vouch for CS3 on the whole. It's just brilliant. We has CS and MX running and the difference of having all-in-one tool box was great
Adobe Bridge makes for easy cataloguing.
The synergy between products is great - Illi-to-flash - Photoshop-to-DW for instance is quick and simple.
The tools are better than ever and I love the feel of it all.
We upgraded on Mac Pro and had no problems - the one PC install we had was XP Pro and there was no issue there either (needed more ram though). Both took ages mind - click install and put the kettle on :)
