Not all Driver will give perfect OC abilities to a GPU.
So, it's very random.

By the way, make sure you Driver Uninstallation is CLEAN instead of DIRTY before you install new driver.
Else, it can be problematic.

Some manufacturers had set their GPU firmware(BIOS) differently.
So, you might not have so much of OCing headrooms via CCC.
Use 3rd Party Softwares like MSI Afterburner.

Naming Scheme is used to mislead and attract costumers.

AMD/ATi had done 2 things currently:
a.) Naming from ATi Radeon into AMD Radeon.
b.) The GPU that suppose to call as Radeon HD6770 will now named as Radeon HD6870. The Radeon HD6870 will be named as Radeon HD6970.

Because naming of the GPU can mislead the consumers sometime.
These companies are too clever. Consumers are mostly ...

Now, they even put crazier slogans, like Military Class or Quality of Choke, Caps and so on. Longer life time.
Or some new technology like Ceramic Coated stuffs. Power phase, power saving.
Hell!!

It can be your Graphic Card Fan's LED.
It also can be your Graphic Card Power Phases LED.

The HSF design(beautifulness) not as good as Radeon HD5000.
It's like a rectangle with a fan and red lines as well as stickers.
Please AMD/ATi, hire better designer to create the HSF. LOL.
GeForce GT400 Series HSF design is more sexy than this Radeon HD6000.

Look like AMD gives us surprise about something called AMD EyeSpeed and AMD HD3D.
I am not sure what is EyeSpeed. But, AMD HD3D is something similar to Nvidia 3D Vision.

It seems the OpenGL improved too. DirectX 11 also become powerful already.

AMD said that this Radeon HD6000 Series have very powerful OCing headrooms.

ATI Catalyst Control Centre will now called as AMD Catalyst Control Centre.

It seems this series doesn't support Tri or Quad CrossFireX Setup.

AMD Rebranding Radeon HD5700-Series into Radeon HD6700-Series. Reviews here, http://www.techpowerup.com/132459/AMD-Rebr...700-Series.html
That's why Radeon HD6800-Series will be Mid-End for this Series. http://www.techpowerup.com/132432/AMD-Rade...-to-Market.html

FYI, Radeon HD5850 can be OCed to the speed of Radeon HD5870 easily.
There's a forumer even flashed the Radeon HD5850 into Radeon HD5870 completely.

I hope AMD will release a Driver that will allow/support Radeon HD4000 and HD5000 to have the ability of AMD HD3D.

Radeon HD4890 is far beyond RM 400. It's around RM 600+-.
Unless, you can get a 2nd-hand Radeon HD4890.

You must be joking that your Metro2033 is not lagging with your single Radeon HD5770... or maybe your eyes got problem or you don't know how to define smooth/or never see something smoother or maybe your FPS demand is low???
Because I tried on GeForce GTX470 and Radeon HD5870. Both also can't get 100% good FPS at all scenes(almost max settings).
Usually, all are OK until those strange lighting scenes. FPS got reduced like crazy by then.

There's "very high" in the selection.
High and Medium in Metro 2033 is pretty low demand compared to "very high".
Also, reviews already show that Radeon HD5770 very far from being able to max out Metro 2033, especially in DirectX 11 mode. Even DirectX 10 and 9, it's also hard already.
If you still insist to say your Radeon HD5770 can play the Metro2033 on almost all max out settings with decent FPS, I would have nothing to say but I would advise you to go medical check up for your eyes.

That's why he's bullshitting. I am not telling jokes.
I tried this game on Core i7 + Radeon HD5870, it's not smooth when everything is set to almost maximal or maximal in some strange lighting scenes.
Also, I tested GeForce GTX470 as well.

Reviews from the internet also shown this games are freaking heavy and CANNOT and IMPOSSIBLE to being max out by a single Radeon HD5770.

Also, angrysnail didn't set everything to VERY HIGH as I mentioned but he didn't realise . He only set High and Medium on 1920x1080. That's why he claim he got decent FPS.
angrysnail, you can try set to VERY HIGH on everything, then, run FRAPS.
ScreenShoot the FPS you got from FRAPS. If you get 30FPS ++ all the way in the games, then, we'll trust you.



Note this, 1650x1050 resolution MAX OUT setting GPU benchmarking for Metro 2033 on DX11 and DX10.
Radeon HD5870 and HD5850 are just getting "playable" framerates and nearly unplayable already. When, 1920x1080? OMG? Reduced even more.
Radeon HD5770? They don't even want to take it to the test. Last time, I did saw a review for Radeon HD5770 on Metro 2033. If not mistaken, it shown that this GPU only can run about 10-20FPS when everything max out.

You need to take care and mention what settings you're on when you're recommending hardware. So, it won't mislead people.
For example and advise:
If Mohammad Ali wants to play Metro2033 with MAX settings and wants to have decent FPS too, but, he got an info from you saying Radeon HD5770 can play this game smoothly and good(you didn't mention what settings you're on in the very 1st place)!
Then, Mohammad Ali will think wrongly and buy something doesn't fit his purpose at all.
So, next time, when telling this kind of things, you need to tell details.

Also, you can clearly see everyone was asking you about game resolution and why their GPU like Radeon HD5850 OCed can't did something like you do. Because you didn't tell what settings you're on and people will automatically implying that you're on almost everything to maximal.

Thanks. Sorry if I had offended you.

Added on October 13, 2010, 9:11 amI know, Metro 2033 sucks.
Story is good, game play realistic but, I still feel it's not right.
Maybe too heavy and too much shaky POV.

No point spending so much on a worthless game like that.
There's still a lot of games with similar graphics quality but with better gameplay out there.
Moreover, they're as heavy as Metro 2033 did.

I would say it's not GPU problem but the game itself is not being optimized nicely.

The stupid Depth of Field(blur far objects) that Metro2033 offered is lame, those are not realistic at all.
Those Depth of Field is only real if your eyes are camera because those are camera effects.
Human Real Eyes don't have DoF(blur far objects), but the farer the objects, the less details and duller color they become only. NOT BLUR.
This kind of effect can be seen in game like BFBC2 and DiRT 2.

The blur effect on far object is unreal in reality. Because DOF(Blur far object) can only been seen or made by photoshooting.
Normal Human Eyes generally don't have this shit.

As I mentioned, Human Eyes DOF is not BLUR OFF the far object but only change the color and texture saturation to lower on distance objects only.
Only the stupid Metro 2033 will do the BLUR DOF(which only can be seen or created by camera ), most games used the Saturation DOF( ).
Not to mention BLUR DOF is lame and not practical but also damn heavy.

Radeon HD6800 seems to be pretty long. I doubt it's same length as Radeon HD5850 and Radeon HD5870 respectively.

I can't imagine if Radeon HD6900 is even longer. OMG.

To FLASH BIOS of a GPU, it carries risks definitely.
If you want to play safe, I recommend you to use MSI Afterburner to OC your GPU. It allows you to OC heavily even without flashing the BIOS to ASUS's(not as gay as MSI) or MSI's(heaviest OC available).

Radeon HD5770 is way shorter than a Radeon HD5870.

For me, current Radeon HD6870 is as long as Radeon HD5870 and Radeon HD6850 is same length as Radeon HD5850.
I can't imagine if Radeon HD6900-Series GPUs will be even longer. Probably same length as Radeon HD5970? LOL?
