Good question. Let me ask another one: how did your own personal video experience change?
Kees
Just purchased a new HP p6510f desktop with internal ATI radeon 4200 video card (128mb) and upgraded to an external ATI HD Radeon 5450 with 1 gb of ram.
ran the windows experience index and found the desktop performance for windows aero dropped from 4.3 (internal) to 3.9 (external), whereas the memory index increased from 5.9 to 7.3 and the gaming graphics increased from 5.3 to 5.9. processor and primary HD indexes remained the same
question - why would the windows aero number drop with the "upgrade"????
