    If you look specifically here: http://www.tomshardware.com/reviews/...0,1915-10.html

    You'll see that even at 1900x1200, High Quality, the framerate from by going from PCIe 2.0 16x to 8x, is 1.3fps....

    Something about the Tweaktown review seems....wonky.

    Main Rig

    Intel Core i7-2600K (SLB8W, E0 Stepping) @ 4.6Ghz (4.6x100), Corsair H80i AIO Cooler

    I refuse to participate in any debate with creationists because doing so would give them the "oxygen of respectability" that they want.
    Creationists don't mind being beaten in an argument. What matters to them is that I give them recognition by bothering to argue with them in public.

    All I know is that we keep saying we won't need the bandwidth, but eventually we're going to get there, so maybe we're finally reaching those limits?

    For my part I know nothing with any certainty, but the sight of the stars makes me dream.

    I heard that ATI Xfire / SLI doesn't support dual screening, what's the story on that?

    HIS HD 4870 is out in Hong Kong

    Two shops in Hong Kong are selling the HIS HD 4870 for HK$2390 / US$306. I don't know about you but I'm hoping our friends in Hong Kong can sell enough of these cards so that AMD has to move the date up to say about July 1.

    Here's an OCW thread you might be interested in.

    Sweet, just chucked my 8800GTS on the market, hopefully 4870x2 makes it out on time or else I'm screwed with no video card to use.

    If this is to be true, looks like the 4870 is a damn fine card.

    Here are a couple more tidbits.

    ASUS Launches World's First 1GB Onboard Memory Version for EAH4800 Series


    The news item disappeared for a time but then came back.

    Hidden in those specs for the HD 4850 cards is a 512MB Asus EAH4870/HTDI/512M card. I need a new leather mouse pad.

    And then there's this from a Canadian online retailer. They have a Sapphire HD 4870 online sale $328.95, no stock.

    That must be where OCW got their images that I posted here.

    I can't find those bar graphs in that translated link.

    Wow
    Looks like a Singular 4870 is nearly up there with the GT280 GTX. and that the Crossfire is near to the 280GTX SLi
    I wonder if ATi crippled their benchmarks using some sort of 3rd tier CPU instead of a Core2Quad Extreme Yorkfield as well.
    If that is the case than a QX9650 on a X-38 will get some serious Crossfire Loving.
    I wonder if some board partners will release 800Mhz versions with custom coolers and 1GB of RAM

    >Zero< AA-^


    ...^

    but yeah not exactly anything to write home about, considering it's a 9800gx2....but,

    the flight simulator with "game AA and AF" whatever settings they may be:

    makes me think that ultra high AA and AF setting may blow yr bandwidth out, in some games.

    even though most of the graphs show virtually NO difference between 8x and 16x pci-e2.0 with a 9800gx2, most of these are done with 0 AA, and or with games like prey and the like that are in the 100fps zone anyway, rather than a crysis like uber graphics bound/bandwidth limit pushing situation.


    but anyway, 85fps instead of 100fps big whoopee do, eh? doubtful that most would notice any bandwidth limitation with 8x8x...
    i guess

    doesn't technically every gfx card use system ram for games to some extent?
