"One important conclusion to take away though is that you don't need a 6-core CPU. They do nothing for your games, so unless you already find a quad-core slow in other applications or your day-to-day PC use, don't upgrade for this reason."
this is the best way to sum up 6 core cpu's lol.
quad cores are where it's at for gaming when you want to multitask as well because there are virtually no performance drops with them like tri cores and hex cores.
a hex core would be awesome for running several virtual machines though
