Hehe, no.

If you don't have any USB 3 ports there's no difference, but it matters for your future motherboard, or if you take your drive somewhere where there's an USB 3 port to hook it up to.
Quote from the USB wiki:
"USB 3.0 has transmission speeds of up to 5 Gbit/s, which is 10 times faster than USB 2.0 (480 Mbit/s) before taking into account that the former is full duplex and the latter is half duplex, giving USB 3.0 the potential total bandwidth if utilized both ways to 20 times that of USB 2.0."
Even if your drive is only 5400 RPM, it's still held back by USB 2.0. With USB 3 you could copy your files as fast as the drive will allow.
Maybe someone who's good with numbers can provide some theoretical speeds.
