While I agree Intels high end cpu's tend to outperform Amd's high ends. If you're looking for a budget gaming build, IMO Amd is the better choice.
Right now you can get an 8 core AMD running at 4.2 Ghz for $210
Intel's equivilent is a 6 core running at 3.9 Ghz for $1029
Now whether or not the intel shows better performance on benchmarks I can't tell you. But I'm willing to bet there's not a game on the market now or in the near future that the AMD wouldn't absolutely crush on Ultra settings.
