    NCIX has several brands of 6870 on sale atm, some in stock, some coming in. Cheapest is the Visiontek at $254CDN.

    I have had good luck with Powercolour, and I like the cooler a lot on their card. Time to update from the 5770 me thinks :O

    Soo... Cheaper than 5870 and almost as fast in games. Looks like AMD did it, can't wait for high-end to arrive. That's where all the spicy things are!

    great to see some new stuff from ATI. We may finally have a price war, great for the consumers.

    The naming thing kinda suck but the price looks right. I'll wait a bit more and hope for a better price.

    Is great to see new AA that has zero performance hit! (see tomshardware).
    In terms of tessellation performance, it still trails Nvidia eventhough it is improved over the 58xx series (see anandtech).

    Overall, great to see something fresh.

    Don't look like these will be great overclockers althought we have not seen any votlage increases yet. Was hoping for 1ghz core without increases.

    Huum go a page further, i have post a screenshot of test by Lab501 ... (6850@1060mhz - 1.25V -stock cooler)

    It seems ATI have keep the voltage low, and just bump it a little give allready nice result ..
    On another forum, someone have allready posted a 1040mhz without increase the voltage on the 6870 ... Offcourse, we will need to wait user reviews and test on a good part of card for know if it's only a minority of card who oc well or not... personnally i can't say it before see more testing about the OC ... it's too early for this.

    how come the 6870 is faster than the gtx 470 only in the guru3D review. in all the other reviews it gets beaten by the gtx 470? fishy!

    Nothing fishy about it ... we used reference cards in this test, some other sites tend to grab factory overclocked products and note it down as GTX 470. Other use different games and that can have an effect as well. Some sites do not equalize driver IQ settings, other test methods (FRAPS) and even other levels in a game can make a difference (we always seek the hard on the GPU segments of a game) and so on ...

    Anyway, don't let our test get in the way of your opinion. But using the words fishy .. well that's just lame.

    Don't think its fishy, just think the Guru3D review is using older drivers, some of the newer ones have bumped up performance with the fermi cards.

    only saying that because I've read another 4 reviews this morning and in every one of them the gtx 470 comes out on top. Only marginally, but still. Fair play if they use different cards/settings...

    It's fishy, but not necessarily from guru3D's side, if others push nvidia cards more to make them look faster than the new AMD cards, then that's fishy too.

    I seriously can't decide whether to grab a 6870 or gtx 470. there was a 6870 on ebuyer last night for £176 but they've pulled it now... hm...

    There were the same complaints that when the GTX400 cards first appeared, lots of people joined to claim a bias etc...

    People should know that no two PC's are the same, and there will tend to be a variance, but as long as the review lists the hardware, and drivers used then you can see that for yourself.

    eclap, don't think it was ever in stock on ebuyer, think that was just listed to generate site traffic.
    It depends on if heat is an issue for you, the GTX470 i think will be faster all round, with more room to overclock, but it will be hotter too, and louder no doubt.

    That's not the case, only for some older cards that applies. The titles we use mostly already were heavily optimized but also titles like Anno1404 etc get way less attention and thus optimizations from ATI and NVIDIA as these games are not a priority, hence we use them.

    I've always tried to find a decent balance to something old, something new and someing less popular games wise.

    But even then ... in 6 months the R6870 will run faster due to optimizations as well, where the GTX 470 pretty much is running maxed out in optimizations already.

    It's the big conundrum of everything + there will always be anomolies.

    cheers for clearing that up Hilbert... I'm leaning more towards the 6870 now. I think I'll wait for the price war to proper start.
