Upgrading a dead Radeon X850 XT 258MB card

The Radeon X850 XT 256MB card in my old desktop just died. I could purchase another one, but I was wondering if there is a better card to purchase that would be an upgrade, yet is still compatible with my old PC.

The desktop is a 2005 Sony Vaio running Windows XP Media Edition (service Pack 3), dual Pentium D 3.00GHz processor, with 1GB RAM. I have a Sony LCD 1280x1024 DVI monitor. The video card slot is a PCI Express X16, but I'm not sure of the version number.

Although the desktop is primarily used for digital mapping graphics, I also like to play the older FPS games such as the earliest Call of Duty (1 and 2), Medal of Honor (up through Pacific), and Brothers in Arms (1 and 2) games.

Would a Radeon X1950 XTX be a good and compatible upgrade or would something else be better/more compatible?

  1. I'd go with a modern upgrade like a 7750. It's compatible and when you want to upgrade other parts of your system it won't slow you down as much.

    Here's the cheapest one on Newegg with DDR5 which I recommend.
  2. zdbc13,

    Isn't the 7750 a version 3.0 PCI Express? Would that be compatible with what is probably a version 1.0 slot in a 2005 computer?
  3. If you could post your mobo model name we could see. PCIe 2.0 did exist in 2005 so you never know...
  4. It is compatible, but there have been problems with select pci-e 2.1/3.0 cards in a 1.0 slot. Would need to know your motherboard.
  5. Using CPU-Z, the listing for the mobo are:

    Manufacturer: Intel
    Model: Prague AAD12395-206
    Chipset: Intel i945P Rev 00
    Southbridge: Intel 82801GB (ICH7/R) Rev. A1
  6. I used to have an x850xt. it might' have been AGP. make sure you have the right card/slot.
  7. They made both PCI-E and AGP x850xt's. If you are just playing the older FPS games then the x1950 should work no problem, but check to see if the card is pci-e or agp, and the only place i could find these cards is ebay.
  8. Keep in mind that the power of the PentiumD is only enough to run a 3850 or 4670. Any gpu more powerful will be cpu bound. If you are running AGP then either of those will need special drivers called Hotfix Drivers since they were not made for the AGP bus so manufacturers used an agp bridge chip on them hence the need for the special drivers.

    If you hace PCIe and want new then I would suggest a 6670. Anything more powerful would be a waste of money.
  9. Popatim,

    I see most HD 6670 cards listed as using PCI-E v2.1. Will that work with what appears to be a version 1 PCI-Express x16 bus?
  10. All versions of PCI-E are backward compatible, so if you really have a PIC-E slot and not AGP you will be able to use any modern card. The biggest consideration after that is power supply. And yes, a 7750 may be CPU bound but looking at the future, you may want to upgrade your CPU and motherboard some day. Or you may want to replace your whole rig. It all depends on your individual upgrade path.

    I think I found a diagram of your motherboard and it looks like you have a PIC-e slot:

    The power draw on either a 6670 or 7750 is about the same. The 6670 is substantially cheaper. I'd go with that.
