I spent a bout 4 hours on having a simple transition with an acceptable performance:
First I tried this code :
left: 2000px;
-webkit-transition: left 1s linear;
-moz-transition: left 1s linear;
-ms-transition: left 1s linear;
The result was terrible on Chrome v21.0.1180.89 and FireFox v15.0.1, but was great on IE10.
I captured the CPU usage and GPU usage graph and found that chrome does not use GPU for basic css properties, 

What is the solution for modern-browsers?
As the result my 4 hours experiments it is better to use transform like below:
This was great on IE10, Chrome v21.0.1180.89 and FireFox v15.0.1.
Note: IE9 does not support tarnsforms
