I'll agree to the extent that there are many other considerations, but I feel it nullifies broad based 3rd party warnings that turning Aero off somehow increases the strain on your over all system.
For example; John has told me many times that turning off Aero
"hurts" our system... but it not true... and it's never been substantiated by any official Microsoft document that he's linked to.
What I infer, is that Microsoft doesn't warn us that turning Aero off
"hurts" your computer performance. Instead they repeatedly, in numerous documents, point out that turning off Aero results in Aero being turned off.
H.P. the largest single desktop and laptop vendor on the planet advises people to turn off Aero when they wish to increase performance. You can easily find the links in their support area... I don't have them at hand. I think that further that suggests that it can't
"hurt" that bad.
