It going to be fast but not super fast .
Like others here said CPU ( i7 quad core ivy bridge ) be 30% faster and video card 50% faster .And 8 GB of RAM and 1 TB hard drive.Do not know how much faster USB 3 is over USB 2.
USB 3.0 is significantly faster then USB 2.0. At this point with Intel supporting USB 3.0 natively, I don't see the point in buying anything with USB 2.0.
I believe theoretical speeds are 10 times faster then USB 2.0.
