The Corsair Vengeance K90 is a sturdy, mechanical-switch keyboard, with an unmatched set of gamer-specific features, including 18 macro keys that can be programmed directly from the keyboard without installing any software. Anti-ghosting and 20-key rollover help make the keyboard more responsive to the right keystrokes and while ignoring the wrong ones. And, of course, there's an adjustable backlight, a USB port (especially useful, since the Vengeance requires two ports for itself), and a removable palm rest. While the K90 is more expensive than the gdgt Must-have Razer BlackWidow, its price is on par with other keyboards in its class, including the Razer BlackWidow Ultimate. If you can live without the backlit keys and extra macro functions, the BlackWidow is still a very good deal. However, if you're serious about PC gaming, the additional features may justify spending more on the K90.
