I get max details and 12x EdgeDetect AA at 1280x1024 on my 4850. I'd bet I could push the res too, if only my monitor supported it. |
Single pcb, multiple gpu. 
Finally got mine, it's a beast indeed, second one is ordered.
The Oblivion installation I have with all graphics maximized 1024x1024 textures and parralaxed + all models added to LOD. 8xAA and 16xAF stable 45 fps, on my 8800GTX, with same system 15 fps...
This really is the way it was meant to be played |

Yeah, Oblivion is on my list of games to experience next...  It's funny because I did the same (install Oblivion) when I first got my 8800GTX. Shows you how good it can look...

Exactly the reason why I use Oblivion, it's the one common game I also used on my 8800gtx, but then I kept on improving it, making the graphics better etc until it became too much for the poor 8800gtx. While I still enjoyed myself, I've also been patiently waiting for something like the 4870X2 |

Just found a 4870x2 for 367,69 € from Club3D
LINK
Anyone here have experience with this brand? good bad or don't matter?.
I don't really care about the cooler and stuff (probably reference anyway) as i will put it under water as soon as the blocks are out.

Ah, crap! a Dutch Gracard company WOW!, did not even knew that the Dutch where doing hardware stuff.
Their website don't look to shabby (don't really matter, but anyhow)

Its not in stock, but ordered it as it will lock on that price. Who knows, they might raise it when its in  . |

I've never had a problem with Club3D cards, so thumbs up from me.
Edit: Anyone with the X2 cards been checking the temperatures yet?

The temps are always on the minus side in all the reviews. Meaning a negative point. I can't find the article just now, but read yesterday that it was one of the hottest cards they ever tested.
When I get mine I will put it on a WC loop of its own, maybe a 260 radiator would be enough.

It's definitely a hot card, but the drivers aren't all up to snuff either, meaning fan control is non existent at this point, people are waiting for catalyst 8.8 this week to fix the issue. Meanwhile people use third party programs like Ati Expert Tool, to control fans and overclock.
If I let mine sit with it's standard dynamic fancontrol it reaches 75 degrees celcius in a matter of minutes and rests at 83. If I however set the fan to 50% it's stable at 43 degrees celcius - 10 degrees cooler than my 8800 GTX on 75% fanspeed.

Ah, so you got yours, cool!. 43c sounds totally ok. My 8800GTX idles on around 48-50c and that with the fan on 100%. |

Oooooh.. you mean a hacked BIOS will allow me to increase vcore without needing a graphite/solder mod on the board!?
Right now the most I can push on the card is 700Mhz on the core and 1010Mhz on the memory .. but even that isn't 100% stable due to the low vcore and vmem. The temps are GREAT right now, using my custom profiles, but I'd really like to push the clocks higher than 700 and 2020 respectively.
(I'm on a Sapphire board, btw)

Yeah there are a ton of modified bios' around. The max Vcore through the bios for the 4850's is 1.2v which is enough to get you near or at 4870 core speeds. After 1.2v I just did the pencil mod and got it up to 1.3v allowing me to reach 800Mhz+ core.
My current bios 3D clocks are set to 725/1100 at 1.2v which the card has no problem doing at all. It also changed the fan profile so that the card in 2D runs the fan faster and the increments between Temp/Fanspeed are narrower/more frequent so you'll hear it gradually speed up. I think mine is set to bump 10% fanspeed every 5C starting from 30%.
Best of all since the 4800's powerplay is sorta non-existant, Asus implemented their own powerplay on their 4800 cards. In 2D they run 150/500 which makes a huge difference temp wise. Most modded bios change it to the Asus 2D clocks.

Yep, same here, ATi Expert Tool. Though about the 8.8 drivers, I'm not sure... Using the beta now, they don't really fix anything. |

Well, I couldn't see any change, so EXPERTool ftw!
Have a question about Edge Detect antialiasing... So I just select 8X (24X) Edge Detect in the CCC, and it will force it in any game, whatever the settings I choose or don't choose?
On a nostalgic note, I remember the first time I used any sort of AA was on my Voodoo 5 5500. It was F[ull]S[cene]AA, and you basically had two options: 2X or 4X. The first game I tried this 'mysterious' option was Project IGI, and 4X was just too much for my HUGE resolution of 800x600, so I used 2X and was amazed at the quality. Now you have all those multi and coverage samples, tents, edges, adaptives and what not...

I personally used the 2nd links bios. I flashed through windows using ATiwinflash, but if you are using Vista make sure you grab the correct version. Painless, took like 2 mins and after a restart I was on my way.
About the Edge detect, yes so long as you set 4/8XAA in a game it automatically uses 12/24X AA samples. This is if you have it set to "Edge Detect" in the CCC. So if you opt not to use AA in a game than no Edge Detect will be applied, but select 8X than you get your 24AA samples. Same with 4X.

That was fuuuuuuuuuuuuuuuuuuun!!!
Ok, note to others who may fall into the same trap.. do NOT use the HardOC BIOS files! They're BROKEN.

I> 4850 BIOS
1. HD4850 Hard Overclocked. DF Core 750MHz Mem 1100MHz Auto Cool Fan.

^^^^^ FUCKED!

Those do NOT work and WILL render your card inoperable! They're missing massive segments of BIOS code and flashing it causes the card to be non-POSTable.
I tried your one, Krazy and it worked like a charm. 720Mhz on the Core, 1100Mhz on the memory. 35% fanspeed after Windows has loaded (it POSTS at 100% and gradually gets slower) so now I'm going to run FurMark to test the OC.
I'm sooooo fucking glad I know my way around my BIOS without needing to SEE. I had to blind-flash the card TWICE thanks to those two fucking BIOSes being shite.
=Edit=
I still don't like the 2D clocks being so low, but I guess that's the price you pay.
=Edit=
HOLY SHIT!! You've GOT to be kidding!? Oh this BIOS is coming off, right fucking now. Dude, the BIOS settings have increased the temperature OVER 25c!!!!!!!!!!!! It's hitting 90c now after 5mins of FurMark. With the 2D clocks (160Mhz Core!? No thanks) it's still 45c idle. That's 5c HIGHER than when I had it at 625Mhz core.
Fuck. That.
=Edit again=
*growls*
And even 5mins after I close a 3D app, the temp is down to 42c and the fan is STILL on 100%! It sounds like a damned airplane :-\
