Not at all. Any computer can easily simulate N gravitationally interacting
bodies using N^2 cycles. My computer could easily handle a thousand-body problem.
The n-body-problem is "unsolvable" because the only way to get an answer is
through an actual simulation. With other problems, you can plug time 't' into
some equation and calculate the result directly.
In other words, a solution to the n-body-problem would require a position
function of 't' that gave an answer in constant time for any 't', rather than
linear time (what it takes to run a simulation).

My ancient Mac Plus could run a simulation of the solar system and do it in
its sleep - although not with General Relativity.
