Hey guys,

I have a gtx770 and 760 laying around, so i wondered if it's possible to flash a nvidia gtx770 to a gtx760 so i can run them in sli.
Basically, they are the same cards, the gtx760 only has some shader units (physically) disabled i think.
Is it possible to kinda "downgrade" the 770 to a 760?

Thanks in advance.
