all i want to know is how was the fit????

i have a pair that will need alot of work make to fit.
i bought them a while ago when they first hit the market
amd told me they did revise the part
but did not tell me what was wrong with it or what was revised.
i don't expect or am i asking for carp back from amd
it was a long while ago when i got them
i don't even remember from where i got them from.

my dillema is
do i go buy another pair
and hope this new revised part will fit
.
or do i take a to them and be happy
i'm not starting with a flat piece of metal

so what luck have people had out there
with this particular part??
