If for gaming, then go for i5 3470. If you are into graphics related tasks like video editing, 3d rendering etc then go for Xeon 1230 V2. Intel i5 has four cores with four threads (one thread per core) plus it has built-in GPU. Xeon has four cores with eight threads (two threads per core) with hyper threading and it does not have built-in GPU. Normally, Xeon is alternative of i7 with all the functionality of i7 but without built-in GPU.
