Slower After Reinstall

Question

So I was having some problems with my iMovie exporting, so I decided to reinstall my entire MBP. After reinstalling I got all my software back onto the system, as well as fully updated. It's smoking fast again and I'm enjoying the speed boost. However, whenever I use iMovie or Audacity, it's choppy to control. Almost to the point that it's unusable.
For instance, before I reinstalled, I could slide my cursor left and right in a 5 second segment of a clip on iMovie and it would play seamlessly. Now it's choppy when it plays. So essentially if I'm seeking a specific spot, I have to wait a few seconds for the cursor to show up on the spot, then play the clip. I can't just slide my cursor to give me a quick play of the video.
With Audacity, when I'm recording the progress bar stalls and skips forward. While before reinstall, it was seamless.
Please help!! This is unbearable! >_<
Edit: Ugh, it's same for Photoshop CS4... I'm sooo mad now..

Any program that requires some power output seems to be limited. Going from work to opening menus, everything seems to run slower.
In Photoshop CS4, if I draw a line, it has trouble keeping up with the cursor. Almost a .5 second lag.
In iMovie if I'm working with a clip, I used to be able to run the cursor over it to preview a clip, now I have to leave the cursor in a spot, give it a second to position the play bar, then I am forced to play the clip, rather than just slide my cursor to preview the clip.
In Audacity, when recording, the progress bar can't even keep up with the recording process.
Everything that requires some power, seems to be sluggish since the reinstall.
Thanks again for any and all help.
