Not really one game. I had a pretty high-end rig in 2007, but I was frustrated to see many games I thought would be awesome go to consoles. Army of Two (with awesome coop) and Star Wars: TFU was coming to every platform except PC. (Of course, Army of Two sucked, and I still haven't played SW:TFU)
On top of that, I was tired of being in the hardware race. When I wasn't upgrading, I was wondering what awesome upgrades I could make.
On top of all that, I wanted an HDTV to play on.
Finally, I decided to sell my rig and buy a PS3 and a HDTV. I ended up choosing the PS3 because it could play blu-ray movies, and I thought it would be able play movies through a Linux partition.
Ultimately, I'm very happy with my choice, but I do miss having a nice rig from time to time. I'll probably get a new one at some point.
