Logitech G9x -->
Logitech have a history of producing good gaming mice and their latest mouse, the G9x, is another great product.
The Logitech G9x is a development of the popular G9 model and boasts a new 5,600dpi sensor (the olg G9 had 3,200dpi).
The unique feature of the Logitech G9x is that it comes with two swappable shells, so you can change the shape of your mouse to suit your preferred style of grip - fingertip grip or resting your palm on the mouse.
It's also got a cartridge system that allows you to customise the weight of the mouse until it feels just right.
Razer Lachesis -->
The Razer Lachesis currently holds the title of having the laser sensor with the highest rate of dpi, rated at 4,000dpi. Its nearest competitors are still running at 3,200dpi so if you really need a sensitive mouse then this is the one to go for! The DPI rating is also adjustable on-the-fly in increments of 125dpi.
It has nine programmable buttons and onboard memory to store up to five different profiles. This means you can plug the mouse into another PC that hasn't got the driver software installed and still be able to access your profiles.
You also get a stylish shape, as well as Razer's typically cool lighting. There are three colours available - Banshee Blue, Phantom White and Wraith Red.
