I can't seem to find accurate information about this anywhere online, so I guess I'll ask it here.
The 777-300ER recently had a range boost to somewhere around 8,500nm, is that correct? If so, that would put it neck-and-neck with the range of the A340-500 (not SIA's 9000nm version that carries less pax)? If there was a topic on the forums about that, I missed it.
Anyway, if the 773ER has a range of 8,500nm, would that make it be able to fly A345 routes? Or is it only in competition with the A346?

Isn't SIN-EWR in the 9000nm range? I wasn't saying their A345 wasn't a special version, it was heavily payload restricted and carried less pax, which it does.

OK,
Maximum range for 777-300ER with a full passenger payload weight of 77,600lbs (361 pax), or ZFW of 447,600lbs. is 7,720nm or (8,878sm).
That range plan assumes standard day temp, zero wind, standard reserves plus allowance. Takeoff weight of 759,600lbs.
Boeing website quotes 7,880nm or (9,062sm), with slightly different assumptions on passenger payload weight.
Now of course this plan has nothing to do with how airlines actually operate the aircraft. In the real world there is wind, weather, route modifications, different seating arrangements, and cargo on board the aircraft. Operators optimize their aircraft to extract the best payload/range/revenue solution possible. In practice it seems that segments of 5,900-6,300nm are at the peak of the curve balancing all three of those factors. This comes out to a nominal payload capability of 115,000-135,000lbs, giving operators great flexibility on what they can put on the plane to make money.
SIA's A345's carry 170pax and are getting around 40,000-50,000lb payloads on the, nominally, 8,300nm (9,545sm) SIN-EWR-SIN route.

OOPS, made a mistake.
TOW for max range for 777-300ER is 775,000lbs

Vimanav,
OOPS again, thanks for the correction I should never post stuff when I'm in a hurry.
