replace HD6770m of HD4670m in late 2009 21.5" iMac

[frankyuan]

I have a late 2009 21.5" iMac and want to upgrade the graphic card. I have found someone have sucessfully done it in a 2010 21.5" iMac.

Also, others have replaced HD6970M on late 09 27" iMac. Can't find anyone done with HD6770M.

Just wondering, it is possible to repalce HD6770m of HD4670m in late 2009 21.5" iMac?

Even if it can, I doubt the cost will be cheap. What's so important you need to keep your iMac?
For the GPU upgrade cost you might want to get a new iMac instead, you could get USB 3, Thunderbolt, and speedier CPU/GPU/RAM? Not to mention 6770m is quite slow?

A 6770 is much faster than a 4670 but the 6970 is better.

Yes. No doubt Radeon 6770m is faster. But the question is, is it feasible?

Sure you can buy iMac Radeon 6970M spare part for how much?

That's right. Plus you need to do the surgery yourself or pay someone else (more money) to do it. We can't sell the old and slow 4670M either because nobody wants it.

Or we just sell the old one and get the new iMac. Along with speedier machine, USB 3, Thunderbolt and full limited warranty intact. That's my point.

thanks for your message. But 6970M is only for 27 inches iMAC as the different type of MXM3. Mine is MXM3 Type A and 27 is MXM3 Type B. So, it can't be use on my mac. Indeed, to buy an new iMac is the best way to upgrade the power. Probably, I will buy the newest MAC PRO in the future. I just enjoy replacing parts for my mac. Gonna buy an HD 6770M on ebay for $300, will post the report later on.
