27" iMac very sluggish after recent software/firmware update

Question

I bought my 27" iMac (2.7 GHz Intel Core i5, 4GB RAM) maybe 6-7 months ago...and it has had NO problems. Even after updating to Lion. Smooth.
But after the most recent graphics firmware update (Feb 29) and software update (late Feb/ealry March 2012...can't remember exact date)...now my iMac is so sluggish! Running more than one application really makes my iMac run slow. And I'm not talking about Photoshop...I'm talking about Firefox, Safari, Mail, iTunes. Basic ones. Especially bad when I play video...very choppy.
Any clue what's going on? I ran Disk Utilitiy (all good, repaired permissions), Clean My Mac, CCleaner...all say good and healthy. So I am at a loss.
Any help would be greatly be appreciated. I'm still under warranty...but I don't think I need to bring it in do I?
Thanks!
