Finally for new features, Logitech has joined Razer and Microsoft in the ever-escalating laser sensor arms race. We're no longer impressed by sensor ratings above 2,000 dpi, as even on a 30-inch display at maximum resolution we fail to see a difference in scrolling speed. For those among you with supernatural reflexes, perhaps these high dpi sensors have some benefit. Comically, the Gaming Mouse G500 and its 5,700dpi upper limit puts it just 100dpi beyond Razer's most recent effort, the 5,600dpi Mamba. Great, we guess.
With all of these new features only adding to the Editors' Choice-winning G5 formula, it might seem like we should just hand Logitech another award for the G500. Microsoft and its Sidewinder X8 disagree. Shooter fans and other twitch gamers will favor the Logitech's 1,000MHz polling rate (which you can adjust in the software), as the Sidewinder X8 only goes to 500MHz. For more deliberate gamers, like players of the Sims, World of Warcraft, or other games where reflexes are less important, 500MHz is sufficiently accurate, and Microsoft sweetens the deal with wireless, cable-based USB charging (so no downtime during recharges), as well as on-the-fly macro recording and Microsoft's proprietary BlueTrack sensor, which lets you use the mouse on pretty much any surface but transparent or mirrored glass.
The G500 is a great wired mouse aimed at performance-oriented PC shooter fans, but we wouldn't blame gamers who don't require that level of top-of-the-line responsiveness for any second thoughts.
