I believe ms have done away with this to keep computer manufacturers happy.
I'm looking for something that does the same as Windows Experience Index (free if poss) but better as I have several pcs/laptops I want to sort out by keeping the best for me and giving the others to various family members.
I don't know much about various processors ,memory etc and can only guess as to the dearest and latest being the best

3 main laptops with windows 8 (have to learn how to work it) are
ASUS K55A 8gb memory
Lenovo g580 6gb memory
Lenovo g700 8gb memory

Sorry - a doddery moment

Just noticed

Try Fresh Diagnose

It's one of a suite of handy free programs from Fresh that I have used for years without any problems.

I've still got Win Exp Index on my PC running Win 7.
Did they drop it in Win 8?

Yes, Windows 8 does not have it.
This machine I`m on at the moment runs Windows 7 and says its score is 5.1.

Mines only 3.3 due to basic graphics card but
I don't play games so not worried.
