PCI-e x16 1.0 GPU: BEST card that is NOT a 2.0 or 2.1

Ok Ok, I've been doing way toooo much research on this topic. I have HP telling me that 2.0 is backwards compatible with 1.0, but other sites saying that it is not. I have some sites saying it IS compatible, but only with ATI and not Nvidia, or the other way around, I don't know. I have some saying it is NOT compatible and a new mobo is needed, which is not an option for me. So...I throw the 2.0+ PCI-e's out the window. I am not about to get it and it not be compatible. I need a PCI-e x16 for my factory, HP a1540n "rig". My question: PLEASE tell me the finest of the dinosaur PCI-e x16 1.0 GPU's that have ever been created on this Earth. I am aware of all the review sites and forums, but, believe it or not, I have not once found a legit answer to this question. The threads always end up being debates of 2.0 and the backwards compatibility to 1.0. Feel free to discuss that, but I am more interested in just getting a decent x16 1.0 card.

Thank you in advance.

  1. Hi, as far as I know you should have no problems running a PCI-e 2.0 card in a PCI-e 1.0 x16 slot...if you are a casual gamer an ATI 5750 should suffice...I myself ran a 4850 PCI-e 2.0 card in a PCI-e 1.0 slot no problems. With a 5750 I doubt there would be any bottlenecks either. Just make sure it fits in your case.
  2. Thanks for the response...I'm looking into getting a used XFX 8800GTS 640 MB with a Zalman cooler on it, and probably cheap, somewhere around 60 I am guessing. It's an x16. Would that be better/safer bet than the 4850? You say you had no problems with the 2.0 in the 1.0 slot. Was that an ATI card? Yeah, I have a factory case so I can't go with anything large either, good point.
  3. Ati or nvidia does not matter, they both conform to the pci-e spec and will behave the same.
  4. Yes the 4850 is ATI. Well I wouldn't think it would make any difference...except that the 4850 would be more powerful than the 8800GTS. I would look into the prices
    of the new 5 series from ATI (or even the ATI 4/Nvidia 200 series if you don't need Direct X 11 support). Nvidia should be releasing their new cards next month...might see a price drop in the 5 series eventually. The 8800GTS should be ok for most of the current games...unless you want high settings.

    Yo lithp,

    I have a 2.0 spec card running on a 1.0 PCI-E slot, dont worry, everything is fine.
    also, a 1.0 card DOES work on a 2.0 slot, for that matter.
    The only difference between 1.0 and 2.0 is double the speeds.

    Now, the card.
    A NVIDIA 8800 GTS for 60 is a good price; however bro, its used, and old technology. its good now, but a couple months down the line...

    better get a ATI 4850 or 4870 or 4890.

    even better than that, get the latest generation stuff, came out just a few months ago, the ATI 5XXX series. Something like the 5770 or better should future proof you for at least a year, though id advise the 5770 as the minimum to get.
    If the 5850 is too expensive, i suggest waiting for the 5830, which should come out in a few days, if not tomorrow.

    finally, whichever card ud get set on, i suggest waiting a few weeks till early march, when the new NVIDIA generation come out. Either they'll have better cards at the same prices, or they wont and u can get ure ATI card. = )

    whtever u get, gd luck.
  6. Let's not forget his cpu is very old, a 4200+ I believe. 5750 would be a good enough match up. Also there might be power supply concerns which rules out some of the higher end cards.
