Sorry, I would have to disagree with the add on card being an advantage. You just lose the pcie slot to get something that's already built in to other boards. If you think it going to save you money down the road it probably won't since when you do upgrade more than likely the new boards will have them. It's a trend that seems to be catching on. Unless you switch motherboards frequently of course then it might be easier to do it that way. But there are lots of wifi cards available, have been for quite some time. The add on card is nothing new but the built in to desktop motherboards is. Matter of choice really. But if a top of the line dual band wifi card is what you want or need then go for it. Nothing wrong with wanting the best performance you can get.
