Z12 and x17 black. I would use them to aggressively open more browser tabs

X20 for wired/wireless option and the Z20 for the quiteness while my family is sleeping. I'd use them to game throughout the evening when I have some peace and quiet.

I'd love if EVGA offered a "tenkeyless" (TKL) model of keyboard, or even better, a 65% :).  The numberpad just gets in the way! I prefer wireless mice, so I'd love the X20 gaming, but it would be super handy if it operated like the Logitech M720 and allowed multiple bluetooth connection remembering.

I like the EVGA Z20 RGB Optical Mechanical Gaming Keyboard 811-W1-20US-KR and the X17 Black wired mouse. I have so many gaming PCs in the house, (4), 1 household PC(I built all these) which are all pretty high-end, some down to mid-range now from age, but then two laptops and I'd swap out one of the older keyboards and mice for my own use and hand me down one of the others for the kids to use.  It works, and keeps all pretty happy. But that's what I'd do.
 
thx for the opportunity to get one.

I drink beer while I play and dinosaur fossils have been found inside my keyboard, so I keep the Z12 for safety.

As for mice, I prefer whatever is wireless, for convenience.

EVGA Z20 RGB Optical Mechanical (Linear Switch) Gaming Keyboard - the LK Light Strike Optical Mechanical Switch is what drew me to this specific keyboard. I don't like clicky keys so linear keys work just fine for me.
 
EVGA X20 Gaming Mouse, Wireless, Black - Sometimes you want your wired mouse to be wireless, and vice versa. The EVGA X20 offers such options. I also like the right-handed ergonomics. I've used ambi mice before; they are usually acceptable but I much prefer a mice designed for the right-hand for comfort reasons. The Quick Responding Mechanism looks pretty cool as well, especially for FPS players. 
 
Thanks!
 
 

X20 wireless mouse.   Need more wireless mice and the Z20 Linear.  No clicky loud keyboards please.
 
 

I would probably choose a Z20 and an X17. The Z20’s audio jack makes it so that a headphone wire doesn’t have to cross any other wires. The X17 has a good amount of extra buttons without going overboard as well as the speed of a wired connection.

I would upgrade my M&K to play Apex Legends with:

EVGA Z20 Linear
EVGA X20 Wireless (Gray)

Z20 would be perfect without the numpad (tenkeyless).

I would choose the EVGA Z20 RGB Optical Mechanical (Linear Switch) Gaming Keyboard because of the quietness and the fantastic RGB lights!
I would also pick the EVGA X20 Gaming Mouse, Wireless, Black cause of the custom profiles and the feel of it.
 
 o/ Jacob hope ya feel better!

I'd pick the Z15 Clicky keyboard (since I don't think the Z20 has hot-swappable switches?)  I'd then take out all the clicky switches to save them for other purposes (e.g. DIY control panels) and replace them with Zilent v2 switches so I can get that amazing tactility and silence. I'm torn between X15 MMO mouse and the black X20 (I also want wireless) but I'd probably pick the X15 MMO mouse since I'd want my wireless mouse to be a vertical mouse for better ergonomics.

i could honestly use this as just a simple quality of life upgrade my current keyboard came from a prebuilt Compaq computer and my mouse is a microsoft trackball 1.0. anything would help my performance in games.

EVGA X17 Gaming Mouse, 8k, Wired, Black, Customizable, 16,000 DPI, 5 Profiles, 10 Buttons, Ergonomic 903-W1-17BK-KR
 
Low activation force and no macro keys for the keyboard and a nice ergonomic mouse for all around great performance. 
Gaming, surfing, creativity.

I´ll use Z20 Linear Keyboard and X20 Wireless Black Mice, just the best of the best for my AAA gaming sessions! Quality is key!

I currently use the Z15 Keyboard and love it. With EVGA Unleashed, I have the color set to a dim, dark orange which looks great with the lights out. Sadly, on pc startup, I do have to unplug/replug the keyboard half the time for it to be recognized, but it could be a mobo issue. Just something I have to deal with. I also have an X17 mouse which looks and feels great, but it has issues, so it is tucked away in a drawer to be used as a backup. Really just waiting for the NU Audio 5.1 to get back in stock.
