IMAC 20" graphics card upgrade/replace

 

can the new IMAC graphics card be replaced / upgraded ?

 

and which cards are compatible ?

and where to get them ?

 

not shure , if they are standard format pci-express cards,

think on the older imacs, there where custom MXM-II cards

If you are talking about the ALUM imacs, you CAN upgrade the video card. They are slot mounted but use different heat pipes. You will need to retain your old heat pipe.

 

I looked over both the ALUM 24 inch and 20 inch service manuals - both models use upgradable cards. You can use a 24" card in a 20" model, but would have to use a 20" heat pipe.

 

Look over www.ifixit.com or service manuals for more info.

I was worried that my 20" silver I mac with the 2400 xt wouldn't play well on Wow. However, just using the stock ram, 1gb and nothing else, upgrading to leopard, updating wow with new update that uses the dual core intel better, I have experienced good play. One area I noticed some lag was in UC near the ogar guards downstairs by the elevators. There are some instances that slow, but I will report when I get more ram.
