No
Usually, I would wait until the ratio is 10:1 of page in : page out to get more ram. Your ratio is 642:1 to give a comparision
A new machine would still be limited by 8 gig of ram on an economical budget (assuming laptop as in mbp forum) and would exhibit the same pageouts
Keep in mind that your current machine will be able to support more ram as the higher density sticks are made IIRC
Page outs are merely when the hdd needs to be accessed when ram is full. The effect can be mitigated somewhat with a SSD drive due to it being much faster than a traditional hdd (though still slower than ram)
