I have the G45, it treats me right, OC genie works, bumped from 2.8 to 3.5 with no problems. IMO if you are going to get an MSI i would recommend the G-55. However, One suggestion is that you should definitely not skimp on a new motherboard.
btw 'll the MSI G45 Mobo unlock my Phenom X2 cores easily with no problems ?
that's nt skimp bro
but i have only this 2 choices atm or any mobo in their price range
