    Hello everyone, this is my first post here at guru3d. So i'm having some video card troubles and I seek some answers. I was told this is THE PLACE for all my video card questions.

    My problem is this, I just recently upgraded (or so i thought) my video card from a

    PNY GeForce 6800 128mb ddr AGP

    to a

    Sapphire X1650 PRO 512mb ddr2 AGP

    So far, my 6800 was performing better the this x1650 has been.

    One of my favorite games, Rise of Nations - Rise of Legends now plays much worse with 10 - 25 FPS with Maxed Settings and no AA.

    Black and White 2, 10 - 30 FPS Maxed with AA X6

    Kinghts of the Old Republic 2 plays the best with anywhere from 15 - 40 FPS. Thats with High graphics setting and AA X4 and AF X4

    These are OLDER games that should be playing great on this system with this video card.

    I have read a lot about these (older ATI AGP cards) and how much of a pain finding the RIGHT drivers can be. So I thought it was just the drivers.

    My first choice were the drivers on the install disk (CCC 9.2), there seemed to work fine but then I noticed the poor performance. So i tried the newest Catalyst Control Center 9.3, still the same. I tried old drives as far back as 7.11 and I even tried to Omega Drivers. But they all work the same.

    So then i thought maybe the drivers are fine, maybe its just this card.
    Could it be true? Could my 6800 128mb ddr perform better on my current setup because of its 256-bit interface as opposed to the X1650 PRO's 128-bit interface, even though the X1650 has 512mb of ddr2?

    Thats the only explanation I can come up with. Can someone confirm this for me? LOL, i'm stumped. Any help and information would be much appreciated.

    The rest of my specs are -

    Athlon 64 X2 5800+
    MSI K9MM-V with 800 MHz FSB
    2GB of Corsair DDR2 800
    Sapphire X1650 PRO 512MB / PNY 6800 128MB
    Seagate Barracuda 320gb 7200 PRM
    All powered by a generic 450w Xion PSU that came with case.

    Thanks for the quick response. Even at 1024x768 and with no AA i'm still not getting the FPS with the X1650 and i was with the 6800.

    Cmoe Tagz, check the link in the FULMTL's message.
    Unfortunately, you are right. Your X1650 has DDR2 and 128-bit memory interface, so the card's texture fill rate and pixel fill rate are actually lower than 6800's (256-bit memory interface). That's why the performance has degraded. RMA the card if you can and look for an HD 3650 DDR3 or 3850 DDR3 (which is the fastest currently available AGP card ).
    Actually, I am also stuck with an AGP board and I'll be waiting for this card to become available:

    What clocks were you running the PNY 6800 at? The stock 325/700 clocks? If so, they'll handle 400/800 the card will actually cool down a least mine did. 10C drop in temp by overclocking it.

    The 6800 has 256 bit memory, the ATI card only has 128 bit memory. That makes a big difference.

    EDIT: Just noticed this was pointed out already....
