I currently have an MSI K9A2 platinum motherboard with a Radeon HD3870 Video Card installed (512MB) PCIe 2.0. I am currently running Windows XP (SP3) with DX9. I would like to upgrade my video card to a better Radeon Card but they all say Direct X 10. My questions are this, can I still run the video card that is DX10 in my system even though I am only running DX9, and is the video card backwards compatible from DX10 to DX9? I cannot see upgrading my OS just to be able to upgrade my video card.
You can run a DX 10 or 11 card on your computer but the capabilities of DX 10/11 will not be enabled in XP ie. the card will work as a DX 9 card in the XP environment.
Thanks. I don't do much high tech gaming and the games I do have are all DX9 and DX9 also supports HD so I'm good to go until I finally give in and upgrade to Windows 7 then I'll already be set with the DX10 video card.
