My opinion is that upgrading to anything more powerful than nvidia 2MX or original Radeon does not make sense unless you upgrade your processor to. The original processor becomes a bottleneck with faster graphic cards. Of those you tested, Radeon 8500 is the fastest. geforce 4MX is pretty mediocre, not worth the effort.
