    I have tried posting this on Lenovo's forums but there is not much activity there so I thought I would see if anyone here has any info. For those not familiar, the G555 is one of the budget laptops. It can be equipped with CPU's ranging from the Athlon II M300 up to the Turion II M540. It has the HD 4200 with 256Mb sideport memory.

    My question is regarding a possible CPU upgrade. I bought one with the Athlon
    II M520. I am 99% certain that it would be a quick and easy upgrade to the Turion II M540. Two questions though...

    First of all, would the performance difference be worth it from the Athlon II M320 (2.1Ghz) to the Turion II M520 (2.3Ghz)? While the M540 is a possibility it seems much more difficult to locate at the moment and two...

    The Turion II Ultra uses the same socket as the Athlon II and the Turion II. As far as I know, they are all based on the Phenom II? Would the Turion II Ultra M620 or M660 work in this laptop or would the bios have some difficulties even though it's compatible with the M520 Turion II?
