orangutan and azriyeti, i have been considering screen resolutions for games too.
I have talked with Mystery on MSN for quite a while regarding resolutions and gaming.
First thing, many here can agree that a higher res like WSXGA+ is good for windows and application/programs.
Now the problem occurs when gaming.
I asked Mystery, why not get a high res screen, and then in the game, tell the game to run at a lower widescreen resolution? His answer is that it will be all blurry. <-hmm true i have heard about this before.
So now, why not take the native res WSXGA+ and make it run at WXGA, and then play the same game and run it at max resolution which is WXGA. < what happens then? (no clue)
I will definately agree with you guys, that the X1600 will not be powerfull enough to run at WSXGA+, but like many here, we don't mind putting the resolution lower aslong as the LCD doesn't blur or ghost.
It would be nice for someone to test this out on any 15.4" WSXGA+ laptop and see what happens on a perticular game.
1) Set native res to WSXGA+, then play a game at WXGA res, see what happens and report to us.
2) Set native res to WXGA. then play the same game at WXGA res, and see what happens and then report to us.

With this info, many of us can then make our purchasing process a lot clearer, and yes the MBP 15.4" with a WXGA+ matte is definately a nice option, a blend of the best of both worlds.
Thanks,
