Can I install an ATI Radeon 6790 2GB in 21.5" iMac?
I would LOVE to know if I can upgrade from my current GPU - AMD Radeon HD 6770M 512MB - to the nicer card offered in the 27" iMac - the AMD Radeon HD 6970M 2GB GDDR5, but I can't find anyone who has accomplished this. Will the 6970M even fit in the 21.5" shell? Is it compatible with the existing hardware? And, most importantly, will installing the 6970M be likely to overheat the system? Please help! Thank you!
Is this a good question?
