Can I add PCIE to new PC to have 3 monitors?

I want to buy a new PC soon and want to clarify something...

I will hookup 3 monitors.. extended mode (not clone)... each have DVI / VGA out...no dmi and no display port.

I have a ATI HD 5670 PCI E video card. ASUS EAH5670/DI/1GD5 Radeon HD 5670 (Redwood) 1GB 128-bit GDDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support Video Card... card has one dvi, one vga and one hdmi out.


my question is:


When I buy the new PC, can I simply add the PCI E into the new box and have BOTH the onbard video card + PCI E working together?

I will need to plug 1 DVI into the onboard card and plug the other 2 DVI/VGA into the HD 5670.

will that work ? OR will the PCI E automatically shut off the onboard video...meaning I can only use the PCI E video card ?? :sarcastic:


Also:

does it make a difference whether the new PC has built in nvidia or ati ? in terms of both working together with the PCI E ?

  1. for a start what video card do you have you have 6750 (which there is no such thing) and 5670 listed in your post...

    you can if you have a built in ATI card and a dedicated ATI card there are some models that support hybrid crossfire.
    Here is a link to AMD's page about hybrid crossfire: http://game.amd.com/it-it/crossfirex_hybrid.aspx
    however it is very picky on what it suports

    As for 3 screens you can not do it with the set up you have you will ether need a 2nd dedicated gpu or a new gpu like the 5700, 5800, 6800 cards that support 3 screens (how ever do do that you will need a Active display port to DVI adapter)

    Most 5570 and 5670 cards support eyefinity, his 5670 should be able to do 3 displays if he gets the Active display port to DVI adapter you mention.

    ATI HD 5670 PCI E video card... I will be adding moving this card to the new PC that I buy...right now im using in an older PC.
  4. So, let me make sure I understand this correctly:

    my ASUS ATI HD 5670 and that will be able to run 3 different monitors at the same time ?

    The 5670 has 3 ports: DVI, VGA and HDMI

    I have 3 DVI monitors... how can I hookup all 3 ? When I hookup a monitor to the HDMI port... the OTHER 2 ports (dvi,vga) stop working.

    So, its either 2 ports: dvi + vga OR 1 hdmi


    Would it be simpler for me to ADD a 3rd video card to the system ? I already own a PCI nvidia 8400gs.


    So, I have a ATI 5670 PIC E and PCI Nvidia 8400GS. Using this setup currently to run 3.

    Maybe it's best for me to stick to this setup?

    the only thing is he did say that "The 5670 has 3 ports: DVI, VGA and HDMI" which would mean that it does not support eyefinity

    it is sounding to me like it would not be a bad thing to stick to what you have (what was it that you wanted to change and why i dont remember you telling us :) ) there are better ways of hooking 3 screens up like using one of the cards i mentioned before

    I am getting ready to buy a new PC in the next few weeks since my current PC is too slow.

    So, just thinking ahead here....and trying to find the BEST way to run 3 monitors as cheaply as possible.


    I suppose I could just stick in the HD 5670 PCIE and the 8400 GS PCI card into the new PC ... and hopefully, everything works the same as it does now.

    But, I was hoping to use the motherboard video card to avoid using the PCI card. The reasons for which are:

    8400 gs is probably slower then a New PC's onboard video card.
    PCI slot will require more power... not sure if new PC's power supply can accomodate 2 extra graphics cards ?

    the best way to do this is get a ATI/AMD card that supports eyefinity. there are versions of your card that do. but i dont think you can ever use the on board and dedicated gpu's ports all at the same time like i mentioned before there is hybrid crossfire but i think even there you have to use the dedicated cards ports your just using the on board gpu to help out with processing. this is the cheepest card on new egg that supports eyefinity so you can run 3 screens off it: http://www.newegg.com/Product/Product.aspx?Item=N82E16814102875&cm_re=eyefinity-_-14-102-875-_-Product
    and here is your card except with support for eyefinity: http://www.newegg.com/Product/Product.aspx?Item=N82E16814102870&cm_re=eyefinity-_-14-102-870-_-Product
  9. I already own 2 video cards: the 5670 pcie and 8400 gs pci card. I DO NOT want to buy another card....so, that is not an option.

    I want to make it work with what I have above.


    Here is the exact card that I have.

    What is crossfire support? can that help me ?
  10. Best answer
    Crossfire is when you link multiple ATI cards together so that they run as one hybrid crossfire is when you link a on board ati card with dedicated ati card. however the ATI card you have does not support hybrid crossfire or eyefinity (which is what you would need to run 3 screens off of one card) what it is sounding like to me is if you do not want to buy a new card stick with the set up that you have if it is working for you. it will be the cheapest way to do it because you already have the parts

    OK - thanks.

    Do you think a New PC in the price range of $800 - $1,000 should be able to support adding 2 cards ? one pcie and one pci.

    I think the 5670 takes up under 80w and the 8400 gs is under 90w.

    On a brand new PC..will a stock power supply be able to run these 2 right out of the box ?

    it depends on the pc many companies put a psu that just barly gets by with the components because it is then cheaper i think in most cases you may want to get a new psu... what pc do you think you will be getting?

    something like this:

    I was looking at getting a processor near the top end... doesn't have to be the best of the best...but I need something near the top end of the range since I use it every day for work - my work consists of opening 35-40 internet apps...each one using some graphics.

    so, im thinking an i7 processor and 8 gb of ram.

    what is the amd equivalent of the i7 ?

    what PC do you recommend around 1k ?

    Is this a good time to buy a new PC....or should I wait a month or so? ( I heard new processors are coming out soon? maybe price will drop ? )
  14. Going back to your original question.

    It IS possible to run 3 monitors using the onboard integrated graphics and a discrete video card.
    I know this because I'm currently doing it.

    ATI has a feature called "SurroundView" which allows an ATI integrated graphics card work with an ATI discrete

    It would depend on what IGP is built into your mobo and whether or not it supports this feature

    Currently I have a Gigabyte 890GPA, with an ATI 4290 onboard and a an ATI 4870

    I am using the 2 DVI ports on the 4870 (1 to a monitor, the other to a TV)
    and the DVI port on the 4290 to another monitor

    Just had to enable the integrated graphics on the motherboard in BIOS

    Hope this helps

    Interesting... this is what I'm looking to do in order to prevent from having to add 2 cards
