I have to preface our article today with the fact that I tend to gravitate to Logitech mice for all of my needs; well not all of them, but that is another story. At this time, we have a bevy of G5, MX518, and MX510 mice spread throughout the labs. In fact, I use the Logitech MX Revolution on my primary work machine and the G5/MX518 products at home. However, I tried a G9 and just did not like it based on how it felt in my hand, but the hardware capabilities were great. I know others that swear by it or various RAZER models, but I tend to prefer the G5 shape. My kids prefer a couple of products from RAZER for gaming and every day use, but overall we are mainly a Logitech family when it comes to mice.

That said, I used the Gigabyte GM-M8000 for the past two weeks in all our benchmark testing and at home. I have to say, this mouse has grown on me in that time. Does this mean it will replace my Logitech units, maybe, maybe not, so let me explain my fence straddling.





Gigabyte is targeting the Logitech G5 as their primary competition in the gaming market with both priced at $49.99 at most e-tailors. The two mice feature similar dimensions, button placement, and overall weight. First off, the GM-M8000 is also tailored for right hand users only.The Gigabyte leads on specifications with 4000 dpi laser engine compared to 2000 dpi on the Logitech. The Gigabyte ships with a 38-gram weight kit compared to 36 grams on the G5. Gigabyte also allows default dpi on-the-fly adjustments of 800, 1600, 3200, and 4000 compared to 400, 800, and 2000 on the G5. But on the G5, you can also add two additional on-the-fly DPI adjustments utilizing the SetPoint software package. Both feature the ability to customize the dpi sensitivity and utilize those settings via the control buttons.

On the software side, the GM-M8000 offers 30 different functions for each of its three buttons (wheel button offers right/left side scroll options for function control) along with three different profiles. The G5 offers the same button/scroll wheel options but with 21 different functions per button assignment. However, the G5's DPI buttons are fully customizable compared to the fixed function on the Gigabyte mouse.

The GM-M8000 features full Macro capability for the five button assignments compared to Keystroke assignments on the G5. Both mice allow the user to set DPI sensitivity on the X and Y-axis separately along with USB report rates. The one advantage that Logitech has is their game detection and profile setup that will automatically configure the mouse with standard button options for a variety of games or you can tailor basic hardware settings per game.





The GM-M8000’s most prominent design feature is its sloped arc and recessed thumb area. The design feels very comfortable for those with average sized or smaller hands. Both sides of the mouse feature a large area molded with a rubber grip that has a nice (almost expensive) tactile feel to it. While the number of buttons first appears to be minimal, the layout design conceals the fact that there are eight available button/wheel choices.

The user can configure the horizontal capable scroll wheel as three buttons (left, center, right). Two additional configurable buttons are located on the left side and a single button on the right side. The single button on the right side is not configurable as it allows the user to switch between the three different mouse profiles with each profile having its own color; red, green, or blue. The right and left click buttons are not configurable. < /p>




The GM-M8000 features the capability to set dpi sensitivity on the fly as discussed previously. The button utilized for this function is located on top of the mouse in an ideal spot. The indent action required is almost perfect for changing each of the four steppings. The 4-degree LED indicator shows the current sensitivity setting.



The overall design of the GM-M800 allowed our hands to fit comfortably in most situations and we never experienced any fatigue or pain over long stretches of game play, Lightwave 9.6, or Photoshop CS4 work. However, those with larger hands will find this mouse smallish compared to the G5. I also thought at times the mouse was too small and the reason being is the tapered rear section of the mouse. The G5/MX518 series fits my palm perfectly and allow me to push the mouse without a thought when required. The GM-M8000 required me to use more of claw hold on it, something I eventually became use to and eventually I did not even think about it.

About the only other ergonomic item mentioning is the first side button (number 4) is placed just a little too forward for most hands. We found forward section of the GM-M8000 containing the right and left click buttons is sloped dramatically (seems to be the standard design style now) but its design ensures a relaxing position for the hand. The tactile feedback when clicking the right and left buttons was very good in our opinion. We liked the motion of the scroll wheel on the G5 better but Gigabyte’s range of motion and gating is more than acceptable for most users. Overall, It is obvious that Gigabyte placed a lot of thought into the shape, quality of materials, and overall mechanical operation of the mouse.





The bottom of the GM-M8000 is ordinary, really, what else would one be expecting besides someone hawking their signature. There are two low-friction Teflon based feet designed to reduce resistance and improve gliding across most surfaces. We found Gigabyte’s feet material allowed the GHOST to glide across our mouse pad or desktop surface just as easy as the Logitech offerings. The user can quickly remove the weight and once removed reveals four slots for the included 38-gram weight kit. We ended up using all 38 grams in testing as we typically like a well grounded mouse. The last area of interest is the sensor opening for the laser sensor. Rated at 4000 dpi, which double that of the G5’s 2000, it proved to be very accurate and flexible in everyday use. We enjoyed the ability customize the dpi as we switched from Call of Duty 4 to Photoshop during testing.

    Hmmm so Anandtech now makes mice reviews...not so long ago this site wouldn't have time to do such a thing as there were actually interesting reviews or articles being made. Sad state of affairs. Miss the good ol days.

    Wow, you are such an idiot. Anandtech always had reviews and articles on anything computer related.
  • aeternitas - Monday, June 15, 2009 - link

    You are an idiot. Stop coming here, we need less of you.

    In 2009, they still make corded mice?

    I HATE cordless mice.

    Aside from the lag issue that makes them useless for gaming, I've never used one that had perfect connectivity. Always replacing batteries or recharging and fiddling with antenna placement :( I'd rather not worry about that crap.

    I hate dumb uninformed comments like these... Razor Mamba = Wireless Gaming mouse 1ms response 5200DPI and its GREAT...

    I HATE computers.

    Aside from taking up the space of a large garage, they are hot and clunky and the hard drives are the size of my refrigerator!

    How about jumping to the year 2009, kid.

    You didn't realize a corded mouse is more appropriate for a high-end product? The lagginess of cordless mice doesn't seem like it's much of a detriment to lower performance mice but the better the mouse the more you notice it.

    Plus, contrary to Gigabyte's idea about adding weights, some people (myself included) want a mouse as light as possible so long as it doesn't effect material or construction quality. Even with a Li-Ion battery you simply cannot build a wireless mouse as light as a corded one when it comes to weight actually moved (entire cord does not move when mouse itself is moved).

    I happen to use a cordless myself for everyday tasks so I don't feel I'm biased when I switch to the corded mouse for gaming.

    What a dumb comment, or I am guessing you have not tried out the Razor Mamba for example. I and my friends cant tell the difference between it plugged in directly or used wireless. Of course having a 1ms response helps I bet. Anyway just because your mouse sucks at gaming and is wireless doesnt give you the right to condemn EVERY Wireless Mouse. Sheesh.

    I should have written you can't build a cordless as light and have the battery last for any good amount of runtime, in theory a radio could be downsized enough that by itself it is no heavier than the amount of cord a corded mouse moves, although all my Logitech cordless mice are still heavier even without the batteries in them, if contrasting once you take the steel weight out of the corded ones that they screw to the top of the shell.
