I don't have enough money to make a difference if I were to move out, but I so seldom get a chance to make a major purchase I savor it when I save up.

1.75GHz Sempron and I would like enough RAM to factor numbers in the second step at least until they get to n=15 million.

DDR-SDRAM
Frequency 166.5MHz
2.5-3-2-7 latencies
(512MB at the moment)

advice welcome, including future-proofing advice)
