(in the spacecraft example, upgrading is defined as:
new spacecraft is manufactured on earth (analogy of newer computers) the spacecraft is teleported to as far as where the old spacecraft went (the interim files from the old computer is copied to the new computer) the new spacecraft continues on the journey (the new computer continues processing the exponent) ) related to MiniGeek's last post: (all completion times based on benchmarks, which may be slightly inaccurate but will do for the purpose) on a pentium 3 996 MHz, M43112609 will take about 307 days to finish. M20996011 will take about 70 days on a pentium 4, M43112609 will take about 42 days to finish. M20996011 will take about 10 days to finish. if you begin on the pentium 3 with M43112609, and later do M20996011 on the pentium 4, it will take a total of 317 days if you begin with M20996011, however, and then do M43112609 on the pentium 4, it will take a total of 112 days so, if you are an average person running prime95, you should test exponents suited to your computer. however, if you really do want to test very large exponents, you should start right now, for you can always upgrade your computer, but continue where your old computer left off.

I've been posting about this in the "Will Any Current 100M Digit LL Tests Finish?" thread (http://www.mersenneforum.org/showthr...662#post154662). Of course, if you have an unlimited amount of money, it makes sense to start as soon as possible and upgrade whenever new hardware comes out. A more interesting question is what you should do if you have only a finite budget for purchasing new hardware. In that case, you should time your upgrades carefully for maximum effect...
