What are you trying to measure? Generally if I'm doing an upgrade of some sort I find a selection of 2-5 benchmarks that are geared toward the item in question. Benchmarking tools are designed to record their results, be reproducible, and be easy to use.
I mean, sure you could make an excel sheet that filled with a huge array of formula's and time how long it takes and record yoru CPU usage and things, but what's the point when you and run Sisoft and Passmark and call it a day (especially if you want to compare your results with others, they just have to run teh same version as you).
