I have been testing out some games on Windows 7 and most games do work without much work I must say. Unless it's just my 4GB corsairs that are keeping me out of trouble. Brothers in Arm's - Hell's Highway works well on this machine. Honestly the load times are even faster then vista so I don't think Windows 7 will have problems with gaming. There has even been talk that Windows 7 will have a more diverse version of DirectX 10.
