Look, it's not that I like the guy. In fact, I see him to be a PITA, but he did ask a question in his post. He went to General Hardware (where it seems everybody goes with whatever off-the-wall question they've got). He also posted in Motherboards because his posts states he wants help in choosing a mobo and chipset. I have no clue why he put it in CPU, but I think you guys are overreacting here.
As for you, Viperbob, there are tons of people that have strong feelings about chip manufacturers (ok, AMD versus Intel...), but those people aren't banned because of that. Was that flamebait? Yes, but it wasn't the entire point of his post. If he wants to turn his back on AMD, then fine, go ahead, but I doubt he realizes how much AMD has done whether he likes their procs or not.
Once again, I can't stand the guy, but that doesn't mean he should be banned this time. If he does it again, then show DocSmarts the door.
