Microsoft Assessment and Planning toolkit

So anyway, I'm trying to use this tool to discover what XP machines are capable of running windows 7 on our network (we've about 105 XP machines left). Now is it me or does it lie ? it's saying that they are all compatible, when I know for sure there are no graphics drivers available for some of them and reading the report it's spewed out I can see driver issues that would cause problems for quite a few machines. I just don't understand why it says YAY EVERYTHING WORKS!
Is there anything better available ?

Are you using the latest version (v8.0)? :confused:

yup,
For instance
Intel(R) 82915G/GV/910GL Express Chipset Family - There is no compatibility data available for this device. For more information, visit the device manufacturer's website.
This is the graphics drivers for quite a lot of machines which afaik don't exist for windows 7 (The machines are 6-7 years old) , of course windows 7 will run but will run in basic mode!
