Can I upgrade the graphics card on my iMac?
I have a 21.5” iMac, 3.06 GHz Core 2 Duo with a ATI Radeon HD 4670 256MB graphics card.
I was wondering if I can upgrade the graphics card to a more powerful one, maybe to the ATI Radeon HD 4850 graphics with 512MB.
And if so, are there step by step instructions on how to do it?
Ist dies eine gute Frage?
