Comparing Performance Across Many Years

So its almost time for me to buy a new machine. I'm checking out the performance specs of the latests MBP on Apple's website and appreciate the comparison graphs they have showing that, for example, Aperture can be up to 1.6x faster than the previous generation.

Now, I am lucky to not have just the previous generation, but a MBP that is close to 5 years old at this point (MBP 2,2). Just out of curiosity, is there a way to estimate my potential gains after purchasing a new computer? An online calculator perhaps?

Thanks,
Alex

 

That's pretty awesome. I will have 4x as many numbers. Sweet.

Performance heavy programs I use are Aperture, Logic, and Starcraft 2. I think I will be sufficiently pleased.

Thanks for your help everyone,

Alex
