Ok i just updated to the 310.70 drivers and got 6755 :D

I have the 680MX/3.4ghz/768gb SSD/16GB, and I only got P6412 in 3D Mark dx11 free/standard version, and P7619 when I overclocked the 680MX to 200mhz+ core/300mhz+ ram with MSI Afterburner. I have the newest NVidia driver v610.90, and Windows 7 x64 with all updates.
Should my score be higher? I see many here get P6700-6800..
Thanks!

The 3DMarks can easily vary a couple of hundred points (at this level) between runs and between different overclocks.
 
+200 on the core, and +300 on the memory made a HUGE difference in Far Cry 3. Where I was getting 37-38fps at 2560x1440, I now get 47-48fps. That's nuts. I still play at 1920x1080 though for the silky smooth framerates.

Also, if you play Far Cry 3 be sure to toggle VSYNC off and then back on to fix a framerate bug in the game for our cards. I found with VSYNC set to on when you load the game, the framerates are quite low by comparison to setting this off.. By switching VSYNC off and then back on, the frame-rate is then identical either way. I do that every time I load the game. Very odd, but it works!
 
Do most games benefit from a higher mem clock or a higher GPU clock. And which one of them requires most regarding temps and power?

I had to back my settings from gpu +225 to +200 for stability. I'm at ram +350.

This is almost desktop GTX 680 stock settings.. amazing..

:) Good stuff, yes. However, we're still quite a bit away from true GTX680 performance though. Putting 680MX in the new iMac was a great move by Apple. Works very well for even the latest, most demanding games! :)
I must admit I've yet to try a prolonged session with the 200/300 overclock, ie. several hours playing some state-of-the-art game like Crysis 2. I'll try that this weekend. Fingers crossed! :D

I get 8259 on +199 core and +290 ram. Results can vary by a between runs though.

Figured what the heck, and ran some 3DMark 2011 benches. This isn't a 100% clean version of Windows 7, with some stuff running in the background, but it's probably a good indicator of the average Windows 7 64bit install.

iMac 2012, 3.4Ghz i7, 680MX, 32GB RAM, 1TB Seagate:

Nvidia drivers: 310.90

Stock core/mem
Result: P6770
http://www.3dmark.com/3dm11/5684938

Overclock: +200 core, +300mem
Result: P8140
http://www.3dmark.com/3dm11/5685030

The buzzing sound from the lower regions of the iMac is considerably louder when you overclock... (still there at stock speed, of course).

That's one heck of a speed difference when you overclock. Quite a tangible difference. I could tell easily the difference playing Far Cry 3 at 2560x1440, but I'm not sure how comfortable I'd be playing for extended periods of time at those clocks!
 
Could someone test the loudness of the fans in the new 2012 iMacs?
I really want to buy a iMac, but it has to be quiet; even when I'm gaming though... Someone? Thanks!

No iMac in the history of iMacs is "quiet" when it's gaming. That's not to say that iMacs are LOUD when they're gaming, but there's a fan in the 2012, and you can definitely hear it when you game. It does depend on the game, though. Far Cry 3 is a fan-worker, but Diablo 3 isn't so much. System is pretty darn quiet playing that one.

I will say the fan is not unpleasant, but it's definitely a moving-air sound. Be sure to keep your expectations in check - it's quite a powerful card in the iMac 27".

Not sure of the reasons, but if quiet is more important than any other aspect of your purchase, I would suggest a custom PC with liquid cooling and a SSD instead of a traditional hard drive. Then your computer would be about as loud as an iPad.

Truthfully though, the noise is hardly noticeable if you get a decent set of speakers or headphones when gaming. I usually have mine iMac hooked up to my 2.1 focal XS speakers and I don't even notice the fan noise when gaming. But it's definitely there, especially if you were playing without sound. Noise is true of any fan-based cooling system though.

Stock desktop GTX 680 has a core of 1000 and a memory of 6000... I think the overclock puts our mobile at 920 and 5600 mhz.. pretty close huh?

I've probably put in 50 hours of play time into these settings... I originally had the core at +225, but two random shutdowns on a warmer day had me reduce the core clock a notch. Using the 310.90 mobile nvidia drivers.

Doesn't the buzzing from the iMac drive you a bit bananas? Or do you just tune it out?

Thanks for your answer! :)
How did you setup the 2.1 speakers on your iMac? I mean, the iMac doesn't have an input for those speakers, right?

What buzzing?

Mine is totally silent. I *haven't* overclocked, but even stock and under high load with my speakers off there is no buzzing sound.

Perhaps the PSU in your iMac has a defect? Sounds like a coil on a transformer or something similar. I would get that looked at under Applecare.

I don't think it's a defect. It doesn't do it in every game. 3DMark and Far Cry 3, for sure it does, though.

A-ha! I did the benchmark again, and I got P6857 (stock speed) and P8291 (OC'ed 200/300).
What did I do differently?
Run the benchmark in streched mode, not centered. Centered gives lower FPS for some strange reason. Puh, now I can relax. Time to play some Crysis with all settings at max in native resolution. :D

FINALLY someone has bootcamp setup and can test this card! Fenn if you can post your 3DMark score here we would all reaaaaally appreciate it. Plus, you will probably be one of the first to run 3DMark on the 680MX (I still can't believe there are no public test results anywhere online, blows my mind).

If you can link the score that works too! I want to see how it compares to the GTX 6XX desktop cards.

you can buy Batman in the App Store you know :), I wanna give Borderland 2 a try and put it to the limit with physicX running :p

No buzzing on mine either in FC3 or 3dmark, just the sound of the fan.

Hmm... really? You sure you just don't notice it? It's coming from what appears to be the bottom left of the system. It's there the whole time in Far Cry 3... It IS pretty subtle, but if you know what you're hearing, it's there. If you have any sound on/don't know what you're listening for, it's quite possible you won't hear it.

By the by, the new Devil May Cry game (if you're a fan like I am) is a fantastic game to show off the iMac. Maxed out at 2560x1400 and 60fps solid (I lock vsync, but I bet it's much higher fps with it off if you can deal with the screen tearing).
