680mx bad performance

I assume you are using bootcamp? Those framerates are obviously way too low. Stating the obvious-alert: Remember to turn off antialiasing when playing newer games in 1440p.

If you're in Bootcamp, install the GeForce Experience and have it check your driver versions and your settings in every game.

Out of curiosity - Win 7 or 8?

To be perfectly honest, outside of the chance you have a lemon, the behavior you describe is close to what you'd get if you tried to game through Parallels/VMWare instead of Bootcamp.

I have a problem with my imac. In every game I own my fps stay in 10-20 range no matter what the graphical settings are, whether it is low or ultra. When changing the settings, image quality stays the same too. The gpu temp always stays about 70C, so, I think it doesn't really know that i'm playing games. The imac itself also doesn't get too hot. Sometimes, the videocard activates and I am able to get 30+ fps in FAR CRY 3(native res + very high settings).
The games i own: skyrim, far cry3, deadpool, tomb raider, dirt showdown, metro last light.
Tried changing drivers from latest whql to beta, but it really doesn't change at all. I'd like to get a response, cause I was really excited while getting my imac and now what i get is simply disappointing(

Ensure you're using BootCamp, as others have said.

Then go on this website: http://www.nvidia.com/Download/Scan.aspx?lang=en-us

Yes, I'm using bootcamp, AA is turned all the way down and it happens even on the lowest settings.
Geforce experience doesn't help at all, tried reinstallin drivers several times.
Win 7 64bit

Can you post the exact settings you're using in these games? Far Cry 3 included. Screenshots are best.

If you're just maxing out every slider it may be that the 680MX just can't do it at 1440p. It's a good card, but some of the games you've listed can be pretty demanding on Ultra.

Try an SMC reset.

On the OS X side, please go into ->About this Mac->More Info and post a screenshot of that. (You should blot out your serial #.)

I can think of a few possibilities, but they're all pretty unlikely:
- You don't actually have the Mac you think you have (mixup at factory or something)
- You somehow managed to enable the Intel integrated graphics on your Ivy Bridge chip and turned control over to that instead of the Nvidia. This happens all the time with the laptops but to my knowledge shouldn't happen on the iMacs.
- You have a lemon.
- Your Windows partition is seriously corrupted.

For fun, and to try to eliminate option 4 above, try to get some FPS numbers from OS X. All the games you listed are Windows exclusive, but you can try WoW (free to play up to level 20) or maybe just the Heaven benchmark tool.

In CS:GO(mac) With native res, ultra and 8x msaa i get 80-300 FPS!!!!

Fascinating.. that puts you firmly in Windows debugging territory.. not enough or too many antivirus software, driver files corrupted, etc. etc. Good luck.. stuff like that is why I stay out of Windows as much as possible..

BTW I was interested in your "About this Mac" information - everything EXCEPT the serial number. There's a (small) risk to you from posting the serial #.

Thnx btw)
It must be my bad windows iso that is causing this.

Or bad drivers.

Use Driver Fusion (http://treexy.com/products/driver-fusion) to clear out the terrible Boot Camp drivers and then install the latest nVidia WHQL drivers.
