OK, according to this page: http://en.wikipedia.org/wiki/List_of_Intel_Core_i5_microprocessors
your processor has an Intel Sandy Bridge core, with avx support. According to this page: http://gcc.gnu.org/onlinedocs/gcc-4.8.1/gcc/i386-and-x86_002d64-Options.html this is the right option (ok, it says corei7, but there is no corei5), if it supports the following: MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AVX, AES and PCLMUL which the Wikipedia page confirms it does (it doesn't mention pclmul, but your processor has the pclmulqdq flag listed in "flags") . So I think it is the best compiler option for your processor. Bill.
