Edit: To make this thread a little more constructive, I went ahead and created a list, using the information from the thread, of keyboards that seem to support at least 6-key rollover, and those that do not.

Playing WOW, you end up using a lot of key combinations. Especially when you start including shift, ctrl and alt in the mix. You would be surprised how many keys you press at once in game. A good example is running using W, spamming abilities using 1-6 and also pressing shift, alt, or ctrl while your run and gun/heal. You might be running into ghosting problems where your keyboard isn't registering all of your keystrokes.. heres a good test to see if you are running into ghosting issues..
This thread is used to test anti-ghosting on your keyboard. Its an easy test, just reply to this thread and do the following..
1. Hold both shift buttons (left and right).
2. Type in the following sentence.. "The quick brown fox jumps over the lazy dog"
3. Make sure to include what keyboard you are using and what interface you are using (USB or PS2).
I'll start.
