    CPU will bottleneck your card by a lot, you should upgrade to some cheap Core2 and overclock it by lots imo.

    How do you set the fan speed ?

    Also, can you set the shader speed independently as you can on the 8800GT's ?

    Thnx

    I think you cant OC SHaders.

    You can edit profile file to set fan speed.
    Now it is set to 30%

    IDLE : 60C
    LOAD : 84C

    So i guess i can OC It more right ? IT was designed to take 100C at least ?

    Make sure your PC isnt close to some wall or something , card needs space to blow the hot air , my PC was very close to wall and i had higher temperatures than now on 45% FAN,
    30% is not laud soo i just leave it that way.
    Will try higher OC later, allmost 8500 GPU score now in Vantage.

    IMO; no...and I wouldn't even try that card with that PSU. It may be good enough, but, I wouldn't trust it.

    The blue storm isnt bad (34amp) and the rig is fine, but all he has to do is ingore those benchmarks :D

    Anyone havin a problem getting the CCC to work with the 8.6? I have tried like hell to get this thing to work.I have xp home with SP3 and the CCC program installs but will not launch,Thought it might be a sp3 problem so I rolled back to SP2 with no luck,I have also tried the 8.5 CCC with the 8.6 vid driver with no luck......What a bummer!!:bang: Im almost at the piont to reformat.:thumbdown anyone have a similar problem like this? BTW when I launch the program I get a "Command line interface" error.

    I have the 4870 in hand, but it's not going in until I get the rest of my new build. D:

    Think I'm gonna order a 4870 now. Would it be better to use the reference cooler cause its dual-slot or my ThermalTake DuOrb?

    Stock cooler is good enough imo if you tweak it!

    You should put it down until you're ready to build. It's going to get all sweaty if you keep holding it! :bigsmile:

    More i use this card more satysfied i am , honestly i wanst even hoping for such a good change, sometimes upgrading nvidia card was causing problems.
    Big supries on the good side :)

    I am playing on low res 1280x1024 , soo i basicaly set max possible IQ i can.
    Even crysis is working with 4xAA and 16AF at this resoultion , big supprise :)

    I am soo happy with the card/drivers performace. I can only recommend it :D
