Basically reiterating what he said, you can't go wrong, but if you want to upgrade to the next generation of CPUs when they hit, AMD will allow you to buy a new steamroller CPU and drop it right in, while intel will require you to buy a new board for either haswell or broadwell.
The difference in 95% of games between the 2 is within margin of error for the benchmarks, which essentially means they're a draw or a wash, and neither one is dramatically better or worse than the other on average.
