    I am planing to buy a Clevo based notebook and at the moment I am stuck on choosing either of these CPU's

    I will be using the notebook for 3d Rendering and CPU performance is a big deal.
    But 2760qm is $160 more than 2670qm. I know it can overclock more and it supports 1600mhz memory... but will I see any real world performance difference?

    Anybody think that it's worth the price?

    If CPU performance is a big deal, it would be worth it.

    The difference between the 2670QM and the 2760QM is ~10% on average. If every bit of power is important to you, I'd say it's definitely worth the upgrade. Especially because of the 1600Mhz memory support, AES, and Vt-d (if those matter to you).

    I'm actually planning on purchasing a notebook from Malibal soon and was looking at these CPUs. For me the memory support, AES and VT-D clinched it for me more so than the speed bump.

    I plan on (trying) to work on my laptop as well as game, and being able to run virtualized work machines with Windows 7 Boot to VHD with optimal performance is going to be AWESOME. :)

    I don't have any idea what is AED and VT-D but they seem good :D

    thanks, It seems 2760qm is worth the money

    AES is the "Advanced Encryption Standard". CPU's that have it enabled will be able to do encryption/decryption and some archiving much faster (Truecrypt/Bitlocker/7-zip all make use of it).

    AES instruction set - Wikipedia, the free encyclopedia

    Vt-d is a feature that builds on top of Vt-x for hardware virtualization. While Vt-x enables hardware virtualization, Vt-d is for directed IO. Specifically, it allows the virtual machine to directly access your physical hardware. On multi-VM clients, it can make for decent performance gains.

    That's great. Always thought the limitation of VM's and local hardware was a software issue.

    Is Vt-x and Vt-d supported by VirtualBox?

    This would significantly improve VM performance.

    They both have AES support
