  1. It isn't tricky. The i5-661 is better suited to enterprises as it includes vPro, Vt-d and Trusted Execution Technology.

    Edit: I meant the i5-660 is better...
  2. There was 3 differences between the Intel® Core™ i5-660 and Intel Core i5-661.
    The biggest difference between them was that the Intel Core i5-661 had a faster clock speed on it IGP (Intergraded Graphics on Processor) at 900MHz vs 733Mhz on the Intel Core i5-660.

    The Intel Core i5-660 has support for TXT (Trusted Execution Technology) and VT-d (virtualization with directed I/O) and the Intel Core i5-661 doesnt support these technologies.
