The chip is soldered directly to the board, so I don't think this is possible.

can confirm that the g750js with the gtx870m is a separate board, i had mine in my out earlier when going through a liquid metal repaste. there are some tinly metal clips that hold it in place that prevent removal, just something to watch out for.
