    Hi if i do a 250/375 overclock to my 680mx i get a lot of artifacts in battlefield 3. The artifacts go away if i lower the overclock to 200/300. Is anybody else having this problem? am i doing something wrong?

    Why do you overclock for bf3?
    I played in 1080p and alle details on high/ultra with good framerates.

    Cause I play in 1440p. Also turning on Adaptive vsync in the nvidia control panel has helped with the artifacts a bit, but I still get them

    Drivers up2date? What software you overclock with?

    Native res. is a lot of stress for the gpu.
    Are there any big differences between 1080p and 1440p?
    If I use Anti-aliasing in 1080p I can hardly see any difference between 1080p and 1440p.

    I can hardly see any enemy at 1080p....
    No but seriously, 1080p with AA is fine, but 1440p without is clearly better...

    I am not sure if you are serious? Of course you will get artefacts and other problems if you overclock too high. Each GPU is different. If you need to overclock, find the highest settings where the machine is still stable (a proper torture test is important!) and then step down the clocks a bit.

    What temps you get while playing bf3 with overclocked gpu?

    Not seeing anything wrong. Like you said, if you lower the overclock to 200/300, the issue goes away. Overclocking is like that!

    Stop overclocking your card at that speed. If you're getting artifacts you might end up damaging your gfx card if you're not careful. Either your card has lower tolerances than others here, or maybe you are not cooling your iMac properly - or both. As always, research before overclocking. Overclocking "blindly" is asking for trouble. Not saying that applies to you, just a general advice...

    I can't understand how people can play in 1080p on a 1440p screen, it looks really bad. 1440p is very demanding for gaming in general. It's really first with GTX780 that we've gotten a decent one-card solution. Hopefully next year we'll get a big gfx update that'll make 1440p gaming more fluid on iMacs. With the thunderbolt2 standard, I wonder if external gfx cards would actually be an upgrade for gaming...doubtful though.

    when you get artifacts, that means your card is trying to tell you something! If I stand in the searing sun for 5 hours, my skin gets burning red, but if I'm only out for 20 minutes, the problem goes away.

    I know you can put 2 and 2 together.

    so can you run Battlefield 3 on 1440p with high settings and have over 30 fps?
    im asking to future prove for Battlefield 4 and next 27" imac with probably 780M(X)
