Vista - can ati and nivida be mixed?

hey can hd3450 card be mixed with nivida onboard? and if so is there anything that has to be done before i put the 3450 in?

I don't know the answer to that but it sure looks like you are wanting to mix water with oil or use Mac & windows OS's in the same partition.

Is there any reason why you want to do that? if you have an onboard nvidia card and you want to use an external (read: agp, pci or pcie) card, I would just DISABLE the onboard card and be done with it.

lol um the 3450 is a pci-e and yes its nvidia onboard lol um my friend wants a new card and i was thinkin of givin him mine for kinda cheap so thats why lol

Sorry but I am now more confuse, what does you trying to sell a card to your friend for cheap has to do with mixing two cards? Is ok if you don't want to explain, I was just trying to help.

i was just making sure it would work before i give it to him lol
because he has nivida onboard

If the bios doesn't auto-disable the onboard video once it detects the PCI-E card, you just need to go into the bios and find the setting to disable it. There may also be a setting dealing with which is the primary display device, if there is just set it to PCI-E.

ok thanks

ATI uses CrossFire. nVidia uses SLI they are two different concepts and connectors.

yes but we are not going to be using crossfire or sli it is a single card going into a single pci-e express slot on a motherboard with a nvidia onboard

ATI has specific instructions on how to install their cards. Firstly uninstall the nVidia drivers and let Windows run on it's basic video driver. Disable the onboard video on the BIOS. Install the video card, restart and insert installation disc and go on from there. If your video card has HDMI output there's also an instruction on how to enable the audio portion if you're connecting to an HDMI monitor/HDTV.
