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?
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.
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.
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.
