There is a program called Sisoftware sandra benchmarking tool that will analyze your computer and compare it to other system specs of your choosing.

There is no one site that tells you what is the most current and best hardware to have because everything changes so quickly, almost every month or every few weeks, Intel comes out with a processor or the price of extra RAM gets cheaper or Apple comes out with a new computer configuration.

I think what your best bet would be is to look at, say, Dell’s website and find a computer you would think about buying if you needed/wanted one now and compare what the basic configuration in that computer with what you have on yours and see how out of date your computer is.

Not really. I mean, you can go to any electronic’s site and view the new hardware. That would be the only way.

These are all the ones I frequent. GPUReview also acts as a data base that links reviews to basically everywhere in terms of graphics.
