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?
Esta é uma boa pergunta?
