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.

이 단계에 사용된 도구: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).
-
-
-
-
Remove the temperature sensor cable from the hard drive. This will allow the hard drive to be removed.
-
-
-
Remove the three T9 Torx screws from the graphics card bezel.
-
Locate the large heatsink from the graphics card, which should be right above the optical drive.
-
Remove the single screw holding it in place.
-
Carefully remove the graphics card temperature sensor cable from underneath the motherboard.
-
-
-
Remove the metal bezel from the graphics card; only a couple of screws hold it in place.
-
Store your graphics card in a safe place in case you need it again or want to reinstall 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 the next step).
-
-
-
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.
-
It's fastened with tape so don't worry about breaking anything.
-
After wiggling and navigating it around the cables, you should have it in your hands.
-
The rectangular space, in picture three where the large cable goes through, use a rotary 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 this step is the heatpipe of the 6 series, which takes more space.
-
-
-
Apply the metal bezel to the new 6 series graphics card. Make sure its aligned properly.
-
Now insert the 6 series graphics card carefully.
-
When in place, fix it with the 3 screws.
-
Reinsert the temperature 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 optical drive with a 256GB SSD, which can be done easily during the installation process.
-
Last tip: If you remove the optical drive for an 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 optical drive is a pain.

To reassemble your device, follow these instructions in reverse order.

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!!
