And the same person who now says 11K+ dpi for the win is also the same person who said a year ago:
""Technology has progressed to a level where you can move your mouse, say, one inch on your desk, and your cursor will move 2 or 3 times your screen length. That sounds impressive for sure, but where is the real value in that?" Rom asked. "That doesn't make you more precise or accurate; I would argue that it does exactly the opposite. A higher DPI in a mouse doesn't offer a lot of value, and it is not a benchmark for how precise or awesome the mouse is. It's simply a measure of sensitivity."
Rom's argument is a simple one: go to a tournament where professional players are in the running for serious money. These are people with something real at stake, who know how to choose their equipment and settings for maximum performance. "Ninety percent of the expert gamers there will be using a DPI value between 800 to 1,600," he said. If you paid some serious money for your gaming mouse, check out its stats: it's likely it can do some multiple of 1,600 at maximum sensitivity."
From the same company that claims to be the "real" gaming company with "professional" gamers that develop their products with them.
The worst thing is deleting the "Don't believe the hype" article from their servers and putting up a "For Maintenance" sign.
