RADEON 9600SE 128MB and ATI 8500

Please can anyone give me there opinion on the upgrade gain from a ATI made Raedon 8500 64 mb ddr and a Crucial RADEON 9600SE 128MB, obviusly there is more ram in the later, but will there be a significant difference, buget upgrade required, so not looking to go high end.

Have a look here: http://graphics.tomshardware.com/gra...004/index.html and http://graphics.tomshardware.com/gra...229/index.html

At the moment for a budget upgrade (casual gamer, doesnt require the fastest, latest) the ATI 9600 seems the way to go, get the best 9600 you can afford and you will be pleasantly surprised with it.
