symptoms of bad clutch?

My clutch is pretty much absolutly gone, and I've been having some driveability issues, and I'm hoping the two are directly related. The car feels sluggish sometimes and it feels like there is a loss of power, could this just be my horrible clutch?

I'm getting a king cobra in the next few weeks, so hopefully the problem will be fixed, but I wanted to see if you guys though that my driveability issues could be because of the clutch.
