Second Gen will usually be better, because they made it bigger, faster, stronger then the first gen i3, here is a CPU Hierarchy Chart to show you that the second gen i3 can keep up or out perform some of the newer AMD quad cores!

The new Sandy Bridge architecture is a lot more efficient than previous models and it's 32nm. But if you're planning to buy a rig with the 2nd gen i3, I would wait for the up coming Ivy Bridge platform.
