I just bought a laptop as well that has the Core 2 Duo processor 2 gig of RAM and Windows Vista Premium. I found that with CS2 that it processed JPEG's extremely fast, but it would not even open up the RAW files. I decided to purchase windows XP Pro X64, which is the 64 bit version of XP Pro.
Here is the site that I purchased XP Pro X64 Full Version for $67.00 shipped from:
www.ebuszone.com
However, I just went there and they do not have it listed on there site, they may have sold out and not restocked.
I do know that zipzoomfly.com has XP Pro X64 here is the link:

However, it is 139.99 there.
CS3 is suppose to work with vista if you just want to hold out and get CS3 and keep using Vista.
