Help me choose please.

I meant 6935G

Does anyone know if drivers for Windows 7 are available for both

For the Acer Aspire, you should be able to get drivers HERE. Just navigate the menu to the proper notebook.

LINK doesn't reveal any Windows 7 drivers for any model of the dv9890.

Could you list the hardware specs of both machines you're looking at?
