Installing ssd as 2nd drive with windows 7, do i need to reinstall drivers?

Right now i have an HDD that has two partitions on it, C for the XP os, and D for storage of games, music etc. I am now going to get a SSD and put windows 7 on it. That way i can use 64bit 7 for the most modern games. Will i need to reinstall all of my component drivers while in windows 7? Or do i not need to because i already applied the drivers while in XP. Not sure if those reside on the hard drive or the actual components.
