Never stopped to think about that to be honest!
Probably not, but hey, maybe so!
I had a Compaq PC I upgraded with an 8600GT 1GB and it blue screened after 3 days of use.
The PSU and everything else was good enough to take up to the 8600, but it still didn't like it.
So I put back in that rubishy 7500le *shuder* and it worked fine.
