What settings are you using for SC2? I played it on High and it was choppy during some levels and cinematics. My computer is very similar to yours, except for the CPU (see my signature).
The only part of the entire campaign that dropped to maybe 20 fps, was on the level with the big laser melting the doors. I sent a group of 20 units right through the laser and it was choppy for just a sec, once I moved past the laser beam it was fine again. I'd say I average around 40-50 fps, but I haven't clocked it.

For me, the level with the worst performance was the one in which there were Zerg Infestors infesting marines and you had to destroy them. They were spewing green stuff, which was what slowed down my computer. SC2 even gave me a warning, suggesting that I turn down the game's quality so that it can run faster.
