If you want an nVidia Chipset for your mobo, go to the
nVidia Website and see what Chipsets they have X64 Drivers for.
If you want an Intel Chipset for your mobo, go to the
Intel Website and see what Chipsets they have X64 Drivers for.
If you want an Via Chipset for your mobo, go to the
Via Website and see what Chipsets they have X64 Drivers for.
If you want an ATI Chipset for your mobo, go to the
ATI Website and see what Chipsets they have X64 Drivers for.
If you want an AMD Chipset for your mobo, go to the
AMD Website and see what Chipsets they have X64 Drivers for.
etc, etc, etc.
Now when you have the chipset you want, go to the
MSI Website and get a mobo with that chipset. It is that simple.
Take Care,
