    A 3870 has 64% of the performance of a 4870. A 5770 performs almost exactly the same as a 4870. So you would probably see around a 36% increase without factoring in CF. The 5770's are going to scale a lot better because they are newer and each new generation scales a little bit better. From what I have heard the 5770's scale exceptionally well. So I would say you would see about a 50% increase, maybe a little more.

    As anandtech pointed out.. why get CF HD 5770 when cost wise, you could get a HD 5850 which would be much better, the CF HD 5770 would on be better in games like HAWKS which have intensive CF scaling so the HD 5770 CF even beats out a HD5870, but that be the only game.

    Either way you cant really go wrong upgrading to the 5k series from the 3k series!

    not a lot of difference in price between the 2 from what i see in the uk tbh , but seeing as all i have to buy is one card i thought why not go for the 5770's lol . well that and my parents will not buy me another 5850 lol

    I am thinking about this investment also, but money is harsh over here.

    The tessellation of DX11 should be the next big thing over anti-aliasing, but it will still pack a punch for a graphics card. Alongside is the cool-looking ray-tracing features it holds which outta turn up some graphics in upcoming games. I can see great reasoning in picking the HD 5000 series.

    The HD 5770 looks very impressive, however I think I should wait it out until DX11-based games show up. I see the next CryEngine to be a challenge for an ATI card, many thank to the morons at Crytek who keep falling for Nvidia. But other than that, I need to see DX11's weight factor before making the next big move.

    I think the cryengine 3 has to run well on ati this time round, ati are really gaining market share with the hd5 series, and that will only improve with the 5770. Also, it's multiplatform across the consoles too, so they will be forced to optimise at least the base code for what will run on the 360, which is an ati based gpu. You could try and argue that for the ps3 and nvidia, but the ps3 has far more power to throw around than the 360, which equals more lazy coding.

    Last I checked the 7800 series GPU in the PS3 can't even keep up... its severely underpowered in the GPU region.

    Whereas the 360 has an R520 with its Tessellation unit activated... essentially at its core with some minor additions to the core...
