    Hmmm n if i hadn't read the reviews i would assume that 6850>5850 and 6870>5870 which is far away from truth, why the like to confuse people?

    Barts (6870) is in reality the follow up of Juniper (5770), with a bit higher price.
    Cayman (6970?) will be the card to replace Cypress (5870), price level unknown.

    A good way to explain it is that they split Cypress (5800's) into a lower group (6800s) and higher group (6900s)

    I don't see it that way, especially if we get a Turcs/Caicos (6770) close to
    Juniper (5770) in performance. In that case I definitely see it more as each card
    is a follow up on earlier generation, but with a inflation in numbers with 1K.

    I have an Antec P182 case with 6 x 12 cm fans in total - 2 for intake, 2 on the CPU, and 2 for exhaust. All the fans are completely silent 1200 RPM coolermaster ones.

    I have used many graphics cards and custom coolers on my cards in this case, and open fansink coolers have ALWAYS conclusively provided around 10-20 degrees lower GPU temps than exhaust blower coolers, unless I set the exhaust blower RPM speeds to very noisy levels.

    My current MSI Cyclone 460's are cooler and quieter than my previous 5770s were with stock cooling, plus my 5770s were cooler and quieter after I replaced the stock coolers with some Zalman fansink based ones.

    Exhaust blower coolers are TERRIBLY inefficient, hotter, and LOUDER than simply having a decent case with lots of silent fans and open fansink coolers on your graphics cards.

    The only part of my PC that makes a bit of noise is the CPU cooler which has a more moderate RPM when the CPU is being stressed. Other than that I can easily hear when the VGA coolers are making noise, and exhaust blowers make a lot more noise than anything else.

    Most fansink based coolers, especially MSI's cyclone perform as well as an exhaust blower running at 4000 RPM, but the fansinks remain completely silent while the blowers sound like hairdryers.

    To be honest, after using my current cyclone GTX 460s, I no longer want to buy any video card again, ATI or Nvidia unless it has this or a similarly decent cooler on it. Reference AMD VGA coolers are rubbish, especially when overclocking. On ATI cards, Sapphire's Vapor X coolers are the best ones you can get, but I also only want MSI or Asus branded cards for the warranty covered voltage tweak and overclocking.

    Calmatory's posts on the previous page explain exactly why this is. Open PCB graphics cards with a fansink design stay far cooler than crappy plastic shrouded exhaust fans.

    Absolutely anyone would think that without first checking the reviews or card specs. However I think that the reason is that the 4700 / 5700 / and maybe 6700 ranges are meant to be 128 bit interface cards.

    4770 and 5770 are both 128 bit cards with much lower Rop numbers. The 6850 and 6870 are 256 bit cards with 32 rops, just with a lower shader count than the 5800 series cards.

    the perf range for the 5k is way differnt than 4k

    the 4770 was better than a 4830, but now we have a 5770 thats much weaker than a 5830, which was just one sucky card, and was way behind a 5850

    the 4 new cards fill in the gap from 5830s up past 5870s.

    No one really knows what Turks / Caicos is going to bring, if at all. The roadmap didn't have Turks/Caicos on them, and for all we know, they may wait to use those for 28nm as testbeds, a'la the RV740.

    the roadmap is only for 2010. And they said lower end GPUs in the 6k family will come at the beginning of 2011, only the high end for 2010.

    You can't look at the prices and still be confused.

    Any intelligent person will always research a product before they buy it. One review of the 6870/6850 shows where it's positioned at in the market.

    Anyone that buys on blind faith.... well, that's the consumers fault.

    looks like it should be a nice upgrade from my msi 5770, just have to decide between the 6850 or the 6870.

    Im leaning towards the 6850. Oc'd it should offer a better bang for buck then the 6870.
    Am i right? What would you guys get.

    the 6850, so much cheaper and can OC just as far with a good cooler, making it very close in perf.

    but coming from a 5770, i would hold off for a 6950 where you can really notice the difference.

    I guess you havent tried 3 x 3d display with Eyefinity setup before?

    Works like a charm, since I just saw it on a trade show in my country.

    cool, how does it look having 3d across screens? does the bezel really ruin the effect? or was it that samsung 2mm bezel monitor array?

    Actually the 3 monitor setup gave me the impression that you get to see more of the play-field then normally. That way I forgot about bezels and stuff very fast.

    I'll admit that one has me a bit surprised... I mean, getting one set of 3d glasses to work across 3 screens with a single pair of glasses would be rather difficult to synchronize the shuttering of the glasses I would assume. On the technical side of things that has to be a nightmare.

    Let me guess. Left 4 Dead 2 or Battlefield? I have yet to see a driver wrapper that has compatibility for more than 1-2 games in stereo 3D + multi monitors on ATI hardware.

    They were using Zalman Trimon 3D monitors, setup on the left side (under sign "AMD HD 3D"):
