HEY ADOBE, WHY IS CS6 KILLING ME?

Question

I'm very unhappy with the performance of CS6. CS5.5 was OK with my setup, but CS6 is virtually unusable.  I thought that if I upgraded my video card, I'd get decent performance, so I got a GeForce 580 (and a new power supply).  The improvement was only marginal.
What makes the product unusable is that EVERY TIME I MAKE THE SLIGHTEST CHANGE, AE has to do this big screen update which takes up to 15 seconds.  IT usually causes the screen to flicker (showing what's behind AE on the desktop.  I was getting this flicker even BEFORE I installed the new video card.) Then I have to click the "MAXIMIZE" button continuously until a click gets through on an idle, and finally I can do something else.  As you can imagine, this makes for pretty slow going.
I've already checked to make sure I have the latest driver and the
latest update to AE.(11.0.1.12)
Is this just a matter of not having a computer thats fast enough?  Or could something else be happening that I could fix without getting a new box?
I don't have a super computer, but its at least average, I'd say.  Here's the setup:

Answer 1

Have you considered simply reinstalling your system from scratch? That by no means sounds normal. CS6 may suck on many levels, but at least the screen refresh works on my end.... Sounds more like a general systemic issue...
