Can you use the cuda support of the nvidia graphic card even if you display the video on another card? Why i would like to do this? Lets think about a nice mainboard with intel onboard graphic that can handle the aero of vista or windows seven but has no support for dxva. Now i can use an nvidia graphic card and use it as primary card but even if its running at a lower clock in 2D mode it will consum much more power than the intel card. And MP is a 3D app so the card will work at higher clock even if its not needed. But if i can use the intel card as primary display i should be able to set a real low clock for the 2D mode of the nvidia card and i would expect the card to be clocked higher if cuda is used. Even it should be no problem to use a nvidia card with 256MB because mediaportal will eat the memory of the intel card.My problem is i use an Scaleo E that powers up its coolers when the power supply needs to deliver more energy. I build in an ATI HD3450 Card and recognized MP displaying the home menu will cause often loud cooler noise. When i close MP the card lowers its clockrate and everything is fine. My problem ist that the cpu is to weak for hd material but with the ati card i have a much higher power consumption. For that i also have to pay.Now how i think it should work. Mp is displayed on an intel gma X3100  as primary display that card can nearly nothing but it´s enough for displaying mediaportal.  I would set a clock of 100 Mhz on the nvidia card in 2D mode should give me a very low power consumption when mp displays the home menu or plays some music. When i start a h264 video with the coreavc codec and cuda support, then the nvidia card should run at a higher clock and decode the video. Even nice would be that i could display hd content with subtitles at moment i can´t. Ok that could been done with the nvidia card a primary card, too.</blockquote>
