Hello
My solution was simple and fast...one computer two os...in the sata2 (1TB) hard disc i install the win7 64 bits...and in the another hard disc ide (80GB) i install the winxp 32 bits. In the startup the computer asks wich one i want to use...the games wich dont run in the win7 i install in the winxp those witch dont run in the xp or for beter performance needs more i...install in the win7!
What can i say...for me its the best of two Worlds!

and no more problems to run my dear SH3 GWX 3.0 Gold... lol
