Wide screen OK, but...I have a widescreen on my Toshiba Satellite P25-609. Nice machine. The original poster asked about games, so he probably won't be running linux much (in the near future). The problem with this computer is that I would like to have linux on it, and take advantage of the nice resolution on the screen. However, nVidia's (I know, I know) drivers aren't too up-to-date to support the widescreen, and I have to run linux under a lower resolution. Annoying!
Maybe things are better now; I don't know. Frankly, I haven't tried it in the last couple of months, so I might be full of silliness right now. However, beware some weird things (like this) which might trip you up when getting a widescreen.
