As a part of our (my gf and I) latest round of Mac buying I just added 2GB to our PowerMac (for a total of 4 GB). 0 Page outs after 24 hours. Life is good. The computer is much snappier, no beachballs, it really makes a huge difference for only $200 (in a 2.5K machine, really not that much money). This is the best price/performance upgrade anyone can make. None of this is news to anyone, just felt like sharing the thrill.
