Xorg using abnormal high cpu in Debian wheezy with official Nvidia GeForce G105M driver of version 285.05

I re-installed my system with Debian Wheezy the other day. And then downloaded and installed the official Nvidia graphic driver for my GeForce G105M card. The driver version is 285.05.09 Certified published on 2011.10.05.
But unfortunately, the system became quite slow with many applications like nautilus, chrome, firefox etc. The symptoms were:
1. It's very slow to open new tab in chrome/nautilus, or to switch between tabs. It could takes several seconds!
