I don't plan on installing Vista while its in still in beta phase. First of all, I don't have the time to reformat and partition just to get XP & Vista together, and unlike my uninformed friend I'm not going to install it over XP...
Oh it is Gnome and KDE. Both are Desktops, but XGI is Xtreme Graphics Interface, that makes you run transparancy and other nice features on KDE or Gnome. That, by downloading the Nvidia/ATI drivers with 3D Acceleration. An intergrated Intel Video could do it. And, of course, if ou have 3D Acelleration, you have WINE and you have Windows Gmes running well
