Großer Leistungverlust bei PCIe x4?

[miRrOr]

(nich dass du deine Karte nachher noch wegen mir kaputt machst )

Keine Angst, ich pass schon auf - aber sollte eigentlich problemlos möglich sein, weil man kann ja auch SLI "installieren" mit einer 2. 7900GT...
Ich werde jetzt Benchmarks machen - erst mit x16, nachher mit x4.
/edit: bin grad am Treiber neuinstallieren - aber ich kann dir jetzt schon sagen . das ist verdammt langsam!^^
/edit2: Nein, stimmt gar nicht - es gab nur soviele Probleme weil der Treiber Probleme gemacht hat... also neuinstalliert, Probleme gelöst
Hier die Resultate:

Man kann einen Unterschied feststellen (vor allem bei den hohen Einstellungen)- aber nicht so stark, wie ich das erwartet hätte!
