    Default Ready to buy video card, which 1 is best of 5 chosen

    <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p>Hello All,</o:p>
    <o:p>(Hope this question is in the correct discussion)</o:p>
    <o:p> </o:p>
    I have my video card selection narrowed down to 5 cards; all are within my price range. I will be buying today after I receive feedback.<o:p></o:p>
    • 4 of them are the HD 4870’s with 512 MB of GDDR5, Core clock 750 MHz<o:p></o:p>

    • 1 of them is an HD 4850 with 1 GB of GDDR3, Core clock 625 MHz<o:p></o:p>
    <o:p>(Am I allowed to post the WEB site?)</o:p>
    <o:p></o:p>The SAPPHIRE 100242-1GL Radeon HD 4850 1GB 256-bit GDDR3 looks like the best deal; twice the amount of memory, but only the MEM is slightly slower. Max resolution, core clock, memory clock, about the same for all 5 cards.<o:p></o:p>
    <o:p> </o:p>
    When I look at the “end-user reviews” on this web site, there are a high number of reviews for the HD 4870 - 512 MB - GDDR5 and only 3 reviews for the HD 4850 – 1 GB –GDDR3. Both 4850 and 4870’s have favorable reviews, but obviously, most buyers opt for the HD 4870.<o:p></o:p>
    <o:p> </o:p>
    Why, I don’t understand?<o:p></o:p>
    Is there really that much performance difference between GDDR5 and GDDR3?<o:p></o:p>
    <o:p> </o:p>
    My video hungry software packages are Flight Simulator X, Punch Home Design, and F.E.A.R.<o:p></o:p>
    <o:p> </o:p>
    Thanks all,<o:p></o:p>

    What size and resolution is your monitor? That makes the most difference in any video card decision.

    remember more RAM doesnt necessarily translate into bigger numbers, only if u plan to play on ultra high resolutions with AA/AF enabled.

    My display’s are
    • Monitor = 22 inches, 1680 x 1050
    • Plasma TV = 50 inches, 1920 x 1080

    After additional forum discussions, I think the HD 4870 is an ideal card for motherboard compatibility and my budget. Flight Simulator X is a demanding game (frame rates, resolution), but from what I read in other forums, it relies heavily on the processor too.

    ATI is coming out with a card called the X2 - R700, possible this month. I may wait and go with this card. The link that was passed on to me is

    A regular HD4870 can easily handle those resolutions. Even my 8800GT can easily handle those resolutions. 512MB of Vram is the sweetspot for now. It'll be a few before we really need more.
