That is a rather broad question. Perhaps you should consider your personal needs first. Are you playing games on a monitor that would need the performance it offers? If you can't tell, you probably don't need it or won't be able to properly appreciate it. There's a guy I know who bought a HD4890 since it came out and just recently I learned he didn't know what anti-aliasing was.

I can afford to buy a HD5970, but with my gaming preferences, it wouldn't be worth it at all.

Ok those with Radeon 5770 please share with me what drivers you're using thx

Sold mine a while back but was running stable on 10.10e before that

Guys, i have problem with my ASUS EAH 6870 GC, hope you guy can give me some advise.

My Thread

Your help is much appreciated.

ok here is some problem pop out after i hav my 5850 crossfire...

-sound control will pop out very slow when u click it
-screen wont be fully cover fully in ur monitor when u dissable crossfire (will left some darkside at the up down right left and when ur mouse go over and cursor will disappear and came back when u not in the dark area)
-aero effect will remain but the smooth pop out effect will gone (instant show the window no more nice effect but glass effect still there)



any1 experience same problem and got fixed ?

why conned?? if he have the budget sure can get 580, its really the fastest single gpu now with nice temp n nice low noise

i just bought a amd hd6970, but my cpu only a c2d e8200, will this bottleneck the performance of this graphic card?

yes, bottleneck by your cpu especially game like crysis

Wanna ask why those 6870/6850 card with Hynix GDDR5 which rated 1250Mhz (5000Mhz effective clock) @ 1.5v in spec sheet can't even pass 1150Mhz without Vmod? Due to heat issue?

Been read alot of reviews on those card, reference design almost all are using those memory, even Vmod done in VR-zone only manage to get <1200Mhz.

What the? 1.5V? You gotta blow your GPU?

Try don't OC now. Or use MSI Afterburner to OC. ASUS SmartDoctor is noob. MSI Afterburner supports all GPUs(all brands). Of course, if it's MSI, it will have more features unlocked with MSI Afterburner.

Haha, no bro, what i ask is the GDDR5 memory, not GPU.

So?

LOL? What? Memory? Even scientist can't count and judge.
How you know about them, then?

Usually, Memory and Core, those stuffs. Won't spoil.
Stuffs that will died are those Capacitors.
You can see this in our Processor, it can last for decades. But, your MOBO will die very fast. Because MOBO is made up by a lot of Capacitors(in whatever size and form) unlike Processor(stable whole chunk of pure metal).

Aiya, no mah...back in last time GDDR3 era, when the chip itself is rated let say 2.0ns, at least stock it will run @ 500Mhz (if OC can exceed that)...but for now the ATI 6870, all the reviewer, even spec sheet stated the GDDR5 can run 1250Mhz @ 1.5V. But somehow the ATI board powr supply to those memory chip adi got 1.6V, then why it need to underclock, and we can't bring back to rated clock with 1.6 stock voltage.

I curious about whether due to heat issue or what only.

hello everyone..i am currently using 6870 to samsung b2430h via hdmi..this morning got some blackout and when the electric is back and i on my pc back somehow the display is not fully fit to the whole screen..currently using the maximum resolution for this monitor..already tried play some games and seems like my 6870 is not affected..is this related to driver problem?

Do you mean the scaling ? Maybe the driver has reset your scaling setting. Try to reset it again and restart your pc. Last time 5000 series user faces this kind of issue before due to driver. But now it is fixed. But i have no idea regarding the 6000 series.

yeah..right now i just set the scaling to overscan for the display to fit entirely..reset means set everything to default is it?

For driver yes.. For yourself no. Actually I'm not quite sure why ATI will reset the scaling back to default even though the screen is big enough for the 100% scalling. XD

Just restart pc and recheck whether the scaling setting is set or not.

For those ATI fans, here some history summary about ATI at Tomshardware

Personally don't really like they renamed to AMD, they should differentiate this two, isn't it?

Any idea how a HD6850 will stack-up against a GTX460 1GB, in games using PhysX? From what I've read so far, AMD cards don't do physX. They were working with Havoc engine before but since Havoc is owned by Intel, I think things didn't work out quite well. They now have OpenCL that is suppose to be "future engine for physics and other stuff" but its yet to be supported by developers and games. On the other hand, titles supporting NVIDIA PhysX are there, and maybe more to come. And from what I've read, when PhysX is on, AMD cards perform horribly.

Correct me if any of my points here are wrong, and please shine a light on this. I have a 9800GT which I want to upgrade, but confused between HD6850 and GTX460 1GB.

P.S. I may go SLI/Crossfire in the future.

PhysX still can be processed by Processor but it's not recommended only.

Games without PhysX title can't use PhysX also. Most of the games out there do not have PhysX title, so, they can't use PhysX offered by Nvidia.

Most games used OPEN SOURCE PHYSICS CALCULATION ENGINE, this mean they'll use whatever hardware(can be both GPU and CPU or either 1) you got to render or calculate the physics of the games/software.
Example:
Bullet Physics and Havok Physics.

So, you can stop your "don't think things didn't work out quite well". That's just your own imagination.

Physics Calculation of a game or software is merely CODING.
It's depending on the manufacturer on what they're into.
Take an example:
PhysX supported(and enabled) games are CODED NOT to perform greatly when you don't have PhysX(Nvidia GPU).
It's a marketing strategic offered by Nvidia basically.

3DMark, a well known benchmarking tools company used to support and partnered with PhysX.
However, now, they had dropped it. Because it's kind of cheating and unfair(get too much score making the benchmark unstable to be judged). It's like you need to make your software(physics calculation) just can run great in Nvidia GPU and run shitty on other hardwares(Intel, AMD).
3DMark 11 officially support Bullet Physics Engine(Open Source) already.
