I'd stay away from AMD processors at the moment, anything by Intel at the same or even lower clock speed will outperform it by a mile!
The graphics on that are quite sub-standard too, don't expect to do any decent gaming with that!
To give you a better idea, this one here
would seem a better choice, even thought the graphics is still not quite there, it's a solid contender in that price range, and the Intel Q6600 processor is a legend...
Better yet, this Dell
one has a decent enough Graphics card if you're not planning on playing the latest games at higher resolutions
