Windows System Performance Rating (WSPR),

Hi guys

My brother brought up a good point.
The WSPR rating for PCs (CPUs, etc) is a moving target.
So, Your PC is fairly good in 2006 with a rating of 3.
If you buy software with a rating of 3 and all should work fine.
But what happens when you buy software with a rating of 3 in 2007,8,9 ?
Will a 2006 PC rating of 3 work with software rating of 2-3 in 2008?
Will the rating hold true until the next version of windows in 2009?

This rating is a good idea, but I see some problems.
I know there is very little info on this now, but maybe it can be fixed before things go final.

thanks!

well dude the reason ppl arent replying is that not alot are on now
