i purchase this sparkle geforce 8400g 512 mb ddr3 pcus with native HDMI Graphics Card to replace my deteriorate 2005 Windows Media Center 32-bit pc graphic card . I swap the old evga graphic card with the Sparkle GeForce 8400 g , I start the pc , and window 7 automatically recognize the change , and download GeForce 8400 g driver from the Nvidia website . I then right click my computer\/properties\/device manager\/display adopter , disabled the old evga driver , and of course enable the new Geforce 8400 g driver . the HDMI port be work well with my 30 '' monitor and thing seem to be work fine . the pc performance have increase from 1.5 to 3.9 and the aero be work . however , I have not see much improvement from switch to HDMI and the booting of the pc seem to be a little bit slower than before . the computer fan be much quieter and I hope the thickness of the card will not cause a capacitor sit right under it to overheat . as at now , life be great .
