I have a Core i5 2500k and this is always HD 3000 graphics. You can also check in an easy way :
Windows 7 right click on desktop - screen resolution - advanced settings - adapter tab shows 'adapter string: intel HD graphics 3000'
TweakNow WinSecret 2011 (freeware) in system information shows intel HD graphics 3000
TweakNow Powerpack 2011 (freeware) system info shows intel HD graphics 3000
Anyway, all programs show correctly the '3000' except CPU-Z which shows the '2000' family. If this program cannot identify this easy information correctly, then I wonder what other bogus info this program gives.
I have deinstalled CPU-Z from my system. I have no trust in this crappy program.
