Question: What's the better? More RAM or a better processor?

Suppose I want to run several systems of equations as below, however, the processing time exceeds 45 thousand seconds (reaching hours of calculations)

• What is better, buying a new processor (new notebook) or buying a new stick of RAM?
• Or does none of this affect Maple? Therefore, it is just a computational disadvantage (the delay time), characterizing the slowness of the program for very large systems as an imminent characteristic.
• Another question: The newer Maples (new versions) seem to be heavier to run. Is it just me? What seems to me is that the previous versions of Maple, because they contain fewer resources, are lighter and run certain calculations faster. Would this be correct?
• Last question: Is it possible to do parallel processing in Maple? So that calculations on huge systems can be run faster

Thank you so much! :)
