I have not upgraded to CS4 specifically because it is so resource hungry. My computer is a quad core that’s only a year old but I already have too much frustration with Prem Pro CS3. I can’t imagine trying to work in CS4.
Recently I had to call Adobe Customer Support multiple times regarding an order of Lightroom I had not received. It was a complete fiasco. Given that delay and the futile attempt at ordering Lightroom on their web site(finally had to place my order over the phone) I’ve lost hope in Adobe.

I agree it’s a good idea to stick to system requirements but doing this does not guarantee anything.
I bought a nVidia 8800GT video card for CS3 because Adobe said they preferred nVidia. Premiere Pro, After Effects, Photoshop & Lightroom all have their individual problems with this card.
I realize my post doesn’t really help the OP but the statement “Whoever built your systems should have read the system requirements posted by Adobe.” reads pretty definitive.
