What's your Windows Experience Index?

[Phyc0]

Quite simply post your Windows Experience Index base score. Feel free to include additional information like I have.

Processor - 4.4
Memory - 5.2
Graphics - 3.7
Gaming graphics - 3.6
Primary hard disk - 5.5

This makes my Windows Experience Index 3.6

What is the Windows Experience Index and where can I find it?
