Wollte nur mal erwähnen das DELL den 302.77 zum Download bereit gestellt hat.
Er ist damit zwei Monate jünger (laut Stempel in der inf Datei) als der momentane angebotene 660M und 675M Treiber.
Das wäre dann der Download zum 680M Treiber beim M17x R4, unterstützt werden folgende DELL / ALienware Karten :
