I would also like some proof of this. I know the 4 series cards were a breakthrough but the last time i heard we didnt have a card that saturated the pcie X16 slot yet. Im talking Ultra /G92 GTS cards. I dont know one way or the other thats why im asking.
im pretty sure myself we still dont have a card that utilizes the bandwidth of pcie x16 1.0 just yet. we might migrate to pcie 2.0 for power reasons but not bandwidth purposes. im thinking were gonna need pcie2.0 when dx11 takes place.
