All down to circumstances. If its my fault in anyway or the other guy was just better then I generally think 'oh well fair play'. If however its down to idiot team mates pulling people my way, blocking doors so I cant get away or pointless spawn systems thats puts you on your own in front of 8 enemies then I rage a little (shout wtf or 'like ****') but havnt rage quit about anything that trivial in years. Only times I can remember is when I was playing a game I really enjoyed and was quite far into but kept dying over and over again due to pointlessly accurate AI (snow level in MoH:AA I think it was) or something similar - really did my head in. Now I just go make a brew.

. I'm sure some of you guys are going to say "get more skills" or something like that
