I recently bought a new system and I had the dual sli cards put in ...I played Doom 3 and the Resurection of Evil on it's highest video settings and it played flawlessley...sorry to have beaten them both now....I was gonna get that microsoft 10 flight sim maybe or oblivion and try them out...but in all games now they play great..1800$ well spent.
