i'm currently using a logitech ps/2 keyboard and have no real issue with it, but i was wondering if there is any kind of advantage to using a usb keyboard - specifically for gaming purposes.
 
If you're talking about a normal (i.e., no special hotkeys) keyboard, then there's no difference in performance.

Some of the USB gaming keyboards, like the Logitech G11/G15, have extra keys that can be programmed for certain games and/or to combine multiple keystrokes... but those are simply added features, not any benefits from using the USB bus. (Then again, some of the gaming keyboards have additional -- often passive 2.0 or 1.1 -- USB ports, and those are a benefit from using the USB bus.)
 
There is no differance at all between ps2 or usb for keyboard use.... period...

Although, some older less quality keyboards may not support pressing 4-5 buttons at once (ie walk forward and sideways while crouching and talking in CS:S, etc.) But most quality keyboards today can support this, and most are usb do to the convienience factor and the fact they can be hotswapped.

edit: now mouse are a different story...
 
I have a Logitech Internet Navigator keyboard, it's USB but I have it connected to the PS2 port with the included adapter. All the extra media keys still work on the PS2 port. I have a Logitech Trackman Wheel connected the same way and all it's extra functions work OK on the PS2 port. I ran them on the USB ports until I needed them for something else. I can't see a difference in performance one way or the other.
 
If you do end up getting a USB keyboard, keep your old PS2 keyboard in case you ever get locked out while it tries to install keyboard drivers or the USB keyboard may stop working in the CMOS.
I've seen the latter a number of times even when LEGACY USB Support is enabled in the CMOS.

As for operation, unless you need programmable keyboard features, you wont notice a difference between USB and PS2.
However, there are some splendid looking USB keyboards like the LED backlit Saitek Eclipse II.
The coloured light shines through the letters on black keys so you can use it at night with the lights off and you get a choice of backlight colours Red/Blue/Purple.
 
thanks all. i've run into that problem with 5 keys pressed at once and it not registering correctly. but that really doesn't happen on a regular basis. i really want a keyboard like my old one by MS. it had 2 usb ports on the back of it so i could plug my mouse into that. none of the KB's that i've seen lately have that without also being amazingly expensive/large/ugly. but if there's no difference, i'm not really worried about it.
 
i have a ps2 kb for when i have to go into my bios. for some reason my g15 doesnt work in my bios
 
No "performance" difference in regards to PS/2 and USB for keyboards. The only time I've ever had a problem with USB keyboards is in regards to them not working in the BIOS. This has never happened on any of my personal machines, it's also getting more rare for this problem, but it still crops up on occasion. If you do go with a USB keyboard, make sure you keep your old PS/2 keyboard around just in case.

Hell, I keep an old AT keyboard around. It's partially for the "just in case" type scenarios but it's also the keyboard from my old Pentium system. One of these days I plan on resurrecting it as a DOS box so it would be nice to have a keyboard that works with it.
