At what point is adding more insulation R-value overkill?

My partner and I are going to use our tax refund to bring our attic insulation R-value up. The new guidelines for our area recommend that our attic insulation have an r-value of 49.
We've gotten two bids for the job. One of the bidders, the one who seemed more observant and on top of things, offered to bring our r-value up to 60 for an additional $300.
Is it worth it to spend the extra cash? Or is an r-value of 60 overkill? Would it be better to keep that money in our fund to replace our antique gas furnace?
