C2 is a later release of the chip in which Intel fixed some minor bugs. As drescherjm mentioned, the C2 stepping correctly utilizes direct I/O virtualization, but, besides that, the difference between C1 and C2 is relatively negligible.

I'm changing to C2 is better than C1

You will not notice a real difference if you are not using the specific feature of virtulization that allows you to assign real hardware devices to a guest operating system like a video card or RAID controller on a virtulization system like kvm, xen or vmware esxi that allows this.
