An anonymous coward writes "Anyone know of good affordable keyboards that are low latency (preferably backed by actual stats)? Low latency is not the same as polling rate.
I had an old keyboard that was high latency (added about 30-50ms more latency when compared to a "gaming" mouse I had!) so I bought a low end "gaming" keyboard[1] which is lower latency but the keys "stick" sometimes (e.g. the system thinks keys are still being held down even though they aren't have to press the offending keys again to unstick them). I don't want to buy an expensive keyboard and find the latency to not be really much better or even worse[2]. And yes 30-50ms can be a noticeable and significant difference in games (2-3 frames).
I've done those reaction time test stuff and I get about 150-170ms using my "fastest" mouse (I have two), 170-190 with my new keyboard and 200+ms with my old keyboard. I see many people get 200+ ( see: http://cognitivefun.net/stat/1 ). At work on my employer's macbook pro I get 220+ms. So it's likely that high latency mice/keyboards[2] and screens[3] are too common. And you can appear to have 50-80ms faster reflexes just by having better equipment.
[1] an A4Tech G800V keyboard, based on one of the few less useless responses from the Other Site when I asked a similar question. Maybe it's faulty but it's going to be hard to prove since it's intermittent. FWIW I got it for half the newegg price and the place I bought it from doesn't sell A4tech mice or keyboards anymore.

that sounds scary. I haven't bought any new computer for many years now, but some rainy day in the future I probably have to - do you mean it can problematic to find a new one with as basic requirements as ps/2 mouse&keyboard connectors today?
Well, when saying "buying computer" I really mean buying a new motherboard, new cpu, new memory etc... is the same problem for that? Maybe I should go look for motherboard now already before it is too late, even though my current one still works fine (and hopefully some more years) and is fast enough for my current needs, so I have it later when I need it?
my requirements
* ps/2 for mouse and keyboard
* printer port
* somewhere pins on the motherboard to connect serial port
* floppy connector
* at least one PATA
* at least two PCI
* no UEFI

If your workload really requires all of that, and you cannot use addon cards or usb versions, then it might be a good idea to buy a motherboard now.
