Intels are faster but besides benchmarks its arguable whether or not you would “see” the performance improvements.
As far as the screens go, the resolution of the screen doesn’t impact whether or not its glossy and I think all of the dv9500’s screens are glossy. I don’t know what videocard you are getting but there isn’t a mobile videocard out there that can play the latest games at 1920×1200 so I suggest getting one of the lower 2 resolutions. I honestly think the 1680×1050 would be the best between having lots of room on the desktop and performance but if you are wanting to play games you are gonna want the lower resolution screen.
