personaly i would keep my XP install IF you might like to play some games

games that are only DX10 at the moment rarely happen

cedega and Wine and CrossOver only support DX9

so most games will work just like thy do in my XP install but sooner or later some games are only going to be DX 10
and i hope people will pettision and pay for DX10 support in Wine and Cedega and or CrossOver

the easyest access point is to allow hardware accsess to the directX Support layer of the hardware and access the additional funtions as part of OpenGL 3
