I am unsure why, but they did their game testing at awful low resolutions which would of course make the tests CPU dependent, or I guess chipset dependent across the control boards. Still I wonder what this proves. Dunno, just thinking out loud....
Yeah...they kinda need to do both to make a point. If it was just a mobo/chipset review/preview, I can't see the point of benching above 1024x768...but it wasn't.
