Hello, I am having display problems and am guessing this is the problem. What can I replace this unit with that doesn't have these heat related problems. Is there another brand that will work in the IMAC 27" 10,1 (2009)? Perhaps NIVIDIA etc...

You can't upgrade an iMac.

Incorrect! The graphics cards are MXM-based and you very much can upgrade that particular 27" iMac.

And here's the part list:

Those prices are INSANE. $478 for a 5750, $598 for 6970M 2GB. Nothing else on that list is even really a worthwhile upgrade for him. Just to replace his existing GPU with a comparable 5670 or 6770M is $214.

I don't know what OP is using his iMac for, but for those prices he'd probably be better buying a new one. Or better yet, building a PC -- a hackintosh if Mac OS is essential.
