Unfortunately, this device seems to need a desktop chipset (Intel X58), so may not even work for a laptop...
In the comments for that one on Amazon, a user mentions that PS3s output with HDCP on the HDMI signal, so this type of unit won't do anything with it directly, but then he also mentions a couple ways around this.
There are others built for the video editing industry, including a model from Matrox, that folks use to record their console gaming sessions, but this class of devices seem very expensive, you'd be better off with buying a monitor, or coming up with some sort of "plan B".
YEP THEY DO.REALLY AWESOME.
I PURCHASED AN ALIENWARE M17X AND IT HAS HDMI IN....THATS THE ONLY LAPTOP I KNOW THAT HAS IT.IT'S A BIT COSTLY BUT DEFINITELY WORTH IT FOR ALL THE FEATURES.
MOST LAPTOPS HAVE HDMI OUT,ALTHOUGH THERE ARE CONVERTERS THAT ARE AVAILABLE.
THEY DONT USUALLY WORK 100% AS THERE ARE RENDERING ISSUES.SOFTWARE IS NEEDED TO ACTUALLY PLAY THE GAMES FROM PS3,SOUND IS ALSO AN ISSUE.THE VIDEO MIGHT WORK BUT MAYBE AUDIO WONT.THERE IS A SLIGHT DELAY OF O.4/SEC WHICH ISNT GOOD WITH GAMES(ESPECIALLY IF IT'S FPS).
