Yes, I've been using that card since last year and that lag is a problem I encounter several weeks ago, It's seated completely with screws stabling it, the card is powered by a 700 watts PSU. I have the latest Nivida driver also.
Hello, I don't even know where should I start because I'm mad desperate here.... Anyways, I had this really annoying aero lag problem on my computer, beside basic animation lagging from minimize and maximize window, the main problems with that lag are music/video stutters while playing...
