If you are using the iMac 27" late 2009 or 2010 model for games, you might want to upgrade your graphics card to the 6 series of the last 2011 model.

Инструмент, используемый на этом этапе:Heavy-Duty Suction Cups (Pair)$14.95
-
Stick a heavy-duty suction cup near each of the two top corners of the glass panel.
-
While lightly holding the suction cup against the glass, raise the movable handle until it is parallel with the other handle (as indicated by the third picture).
-
-
-
Gently lift the glass panel perpendicular to the face of the LCD, enough to clear the steel mounting pins attached along the underside of the top edge of the glass panel.
-
Pull the glass panel away from the lower edge of the iMac and carefully set it aside.
-
-
-
Carefully lay the iMac stand-side down on a flat surface.
-
Use a thin hooked tool to lift one side of the top edge of the display by its steel outer frame.
-
-
-
Using your fingers, carefully pull the vertical sync cable out of its socket on the LED driver board near the top left corner of your iMac.
-
-
-
Squeeze the two display data cable connector arms together to unlock it from its socket on the logic board.
-
Pull the display data cable connector away from its socket on the logic board.
-
-
-
-
Rotate the display out of the outer case enough to disconnect the LED backlight power cable from the LED driver board.
-
-
-
Lift the display for enough clearance to disconnect the LCD thermal sensor cable connector from its socket on the logic board.
-
-
-
Carefully pull the display toward the top edge of your iMac and lift it out of the outer case.
-
-
-
Be extra careful with the display cables, I broke mine.
-
You need to remove the temperature sensor cable from the HDD to remove the card.
-
Remember the position of this cable! ifixit tip: it must later be reinstalled closest to the SATA connector and the black cable need to point up, towards the LCD.
-
-
-
Now remove these 3 T9 Torx screws from the graphics card bezel.
-
Locate the large heatsink from the graphics card, which should be right above your DvD drive
-
Remove the single screw there holding it in place
-
Carefully remove the graphics card temperature sensor cable from underneath the motherboard
-
-
-
Slowly and carefully pull the graphics card up and away from the motherboard
-
Make sure the metal bezel of the card doesn't scratch the motherboard
-
You should be able to remove it easily and when you removed the temperature sensor cable you have it safely in your hand
-
-
-
Remove the metal bezel from the graphics card. Only a couple of screws hold it in place
-
Store away your graphics card safely in case you need it again or want to reinsert it
-
The second image shows both the 4 and 6 series side by side. A little difference in height makes some extra work necessary (see next step)
-
-
-
You will need to remove the DVD drive in order to remove the plastic piece mentioned in the next step. The drive is held in by 4 Torx screws, once those are removed, the drive can be lifted and swung out of the way without removing any cables.
-
-
-
As the 6 series is slightly higher we need to make a little space on the plastic holder which is beneath the card
-
Remove the plastic part which is shown on the 2nd picture by removing one screw and carefully pull it from the aluminium case
-
Its fastended with tape, so don't worry, you can't break anything
-
Some wiggling and navigating it from the cables and you should have it in your hands
-
You see the rectangular space where the large cable goes through. Use a saw or other tool to make it about 5mm wider and 2-3mm deeper
-
The third image shows the final result we want to achieve
-
The primary reason for thi step is the heatpipe of the 6 series which takes more space
-
Note: this is ONLY necessary on the late 2009 model, 2010 models already got enough room!
-
-
-
Apply the metal bezel to the new 6 series graphics card. Make sure its aligned properly
-
Now insert the 6 series graphics card carefully.
-
Make sure you don't damage the upper side of the mother board when reinserting
-
When in place fix it by the 3 screws
-
Reinsert the temperatur sensor cable. You need fine hands or a good tool to do so. Be patient with this step
-
-
-
Reassemble the LCD display as explained on ifixit.
-
No other work needs to be done. As you removed the power cable the SMC should reset, which is the chip configuring your hardware
-
If all goes well you should be greeted with a welcome screen and "about this mac" should show the image to the left
-
Note: I also replaced the DvD drive with a 256GB SSD which can be done easily during the installation process
-
Last tip: if you remove the DvD drive for a SSD make a minimal bootcamp partition and install windows on it. It will save you a lot of trouble if you ever need one. Believe me, simply do it, installing bootcamp with no DvD drive is a pain.

works perfectly ;-) just be slow and precised
Just be noticed that this upgrade not work for iMac 27 late 2009 equipped with core 2 duo CPU, but only with the i5 and i7 CPU one!

Did you know you can add an additional SSD drive WITHOUT needing to remove your Optical drive? It installs vertically just to the right of your HDD. I just performed this upgrade last weekend. I believe you can do this to 2009 and up models.
Regretfully Not on the iMac late 2009, because the motherboard has only 2 SATA ports, not 3 like the 2010 and later models...
Just a question: with this mod, are you able to use Airplay Mirroring in Mountain Lion? Since the inhability to use it on these macs is GPU-related, virtually with this Graphic card you may be able to enable it... Let me know please!!
