    D975XBX2kr PCI Express & GPU compatibility inquiry


      Hi there everyone,



      I've been gaming for quite some time now and I recently been  experiencing issues with my Gaming Rig. I'm currently on the diagnostics  stage. So far tests show that the source of my problem might be my GPU.  I have a 2.75 year-old eVGA e-GeForce 8800 GTS 512MB DDR3 PCI-Express  installed on my Intel D975XBX2KR Socket 775 ATX Motherboard. If you look  @ it's TechProdSpec sheet, you'll notice it's a PCI Express 1.x x16  (electrical x16 or x8) bus add-in card connector. PCI Express 1.x  GPUs seem to be no longer available.


      So here's my inquiry:


      I need to know (and be certain) if PCI Express 2.0  and/or 2.1 GPUs are fully backward compatible with my current  PCIe 1.x motherboard.



      • If the answer is NO: Well, that's too bad. Guess I'll have to start saving for my next Gaming Rig built.
      • If the answer is YES: Great! I would really appreciate if you can advise of some GPUs models to replace my old 8800 GTS 512MB.


      Please have the following in mind:



      • GPU usage: HD Video, Hardcore Online HD Gaming.
      • Budget: up to $275 USD.
      • Supported tech: DirectX 10 and/or DirectX 11 compatible. Not interested in SLI (my Motherboard doesn't support it) or CrossFire.
      • Concerns: I don't mind noise but heat is a big concern.


      Since system specifications are important, you can find my Gaming Rig's specs below.



      All your help is most appreciated. Cheers!
