Win7 will install pretty much every driver that you need. I am typing this on my SXPS 16 and it worked great. It just knew what to download. The only ones I had to get new ones of were when Dell put up the new drivers for the stuff I am using (I did this with a RTM build before Win7 came out). Just let it do it on its own. Then I would recommend doing the video driver and possibly the internet one (those were the ones I noticed improvement with).
