So can anyone please explain: Will a Core QUAD CPU with 4GB RAM do it much faster so that it will be worht to buy it? Is Rapid ready to use those HT multitasking skills or it will be better to buy 8GB RAN for the old configuaration?
It is a popular misconception that things have an absolute value, and a silly one. A thing is worth what someone will pay for it, not one cent more. Banks thought that subprime loans were worth what their models said, oops. All I can say is that more memory helps, I work on 12G, and muti-core helps on optimisations and validations, but only
for the commercial version of RM. So you might, as they say, be missing the elephant in the room, in that the commercial versions cost more than the hardware necessary to run them.
