Looking for 360 installation guide

I'm trying to find the guide that would help me decide which games to install on my hard-drive.  I remember seeing a really good one which showed whether they helped, did nothing, or did worse by installing them.  Hoping someone here knows what I am talking about.  The website had a black background with 3 different colors that showed which of the 3 effects it had. 

This probably isn't exactly what you saw, but it seems similar.

EDIT: That list hasn't been updated in a while.  A recent update made some games take up less space when installed than they did before.

yea, i saw that and
