Upgrading new GPU over integrated mobo graphics

Hypothetical situation --
I want to buy a new AGP GPU, ie GeForce 4 Ti, etc., and put it in my Sony Vaio, which did not come with a graphics card, but with on board integrated graphics -- Intel Extreme, or some such nonsense... Now, I wonder how these two components working together will operate - will simply installing the new card be all that it takes, or do I have to disable the mobo graphics -- will the two work together in some way for increased graphics processing, or will the two somehow cancel each other out? Maybe even making my new GPU unviable?

  1. Well, the Ti4200 will definitely increase your performance...I would think by a factor of 4 or more. Just as an example, my office computer with a 2.5GHz processor and intel integrated graphics scores around 3000 points on Aquamark3 while my old home computer with a lowly 1.4GHz celeron scores over 20000 with a Ti4200.

    You shouldn't have any problems installing a card, Windows should autodetect it and will try to install its own drivers. You can let that go ahead and then update them later, or download the latest drivers first and cancel the auto install wizard and install the new drivers.

    There may be some options in your BIOS to disable the onboard graphics, but most newer boards will do that automatically when you plug in the card.

    Do you know for sure that your motherboard has an AGP slot?? I don't know anything about the Sony computers. If it doesn't you'll need to go with a PCI card, which, while being far below the AGP in performance, will still offer significant improvement over your integrated chip.
  2. You'll wanna make sure the Vaio has an AGP slot...I've run into quite a few prebuilts with integrated graphics that just don't have them and I end up having to install a PCI Vid Card. But you shouldn't have any problems with windows as long as the integrated graphics is BIOS disabled and you have the BIOS set to NOT try and force plug and play.

  3. I doubt you even have an AGP slot to plug such a card into, the last VIAO I worked on did NOT. You could open the case and look, the PCI slots are white and the AGP slot should be at the top, the same length as a PCI slot, and brown. A short brown slot at the top wouldn't be AGP, but CNR or AMR.

  4. The two will NOT work together. You have 2 AGP trying to take one AGP bus port. When you do get the new AGP card. First uninstall the AGP drivers, then go into the bios and disable the onboarg agp, then shut the rig off. Afterward just plug in the new card and install its drivers. That will get ya going.
