In the pilot episode, there's a brief conversation between both when Nick asks Greg if he has a Dreamcast.
I got this from "Elyse: CSI Site" (http://members.aol.com/JRD203/csi-episode-000.htm):
"Nick is apparently a videogame buff. He asked Greg if he'd gotten the NFL-2K for Dreamcast yet. Of course he had. He got it the day it came out! Greg's team is the Falcons, while Nick chose Randy Moss."
