Mid-2011 27" iMacs: 6770M reliable?

I know Apple has a replacement program for the affected 6970M cards, but I have a chance to buy several Mid-2011 27" iMacs with the 6770M cards. Are these machines reliable? Or are all Mid-2011 27" iMacs problematic? Would be using them personally (not for re-sale), and might pick them up if they're not susceptible to issues like the 6970M machines.

Just wanted to hear from someone more experienced in working on them. I don't work with iMacs, only MB/MBPs. Thanks!

They are so-so. These GPUs will still fail but not as common as 6970. At least the 6770 chips you can find new if you want to fix it.
