We won't know for sure until the DAMN HL2 Bench and Det 52.10's come out. Of course if freaking people could keep thier words (Valve/Vivendi/Nvidia) the we would alread have our answers (as Valve had said that HL2 & HL2 Bench would be out 9/30 and Nvidia said Det 50's would be out BEFORE that). I personally think there is some serious scrambling to get this thing playable on Nvidia cards (Valve and Nvidia working on optimizations). I don't care WHAT Gabe said, he can't alienate a company that represents such a large part of the games's customers. Hope it comes out soon though...at least the bench. I wanna see what my crappy 5900U can pull of...lol.
