The CPU is decent. the 820D is 2 2.8 ghz CPUs with 1MB cache each. Not a record setter for FPS, but will be very good for mutlitasking.

x600 is soso, not great.

The important thing here is how much you are looking at paying. Its a solid system, and could represent a good value.

If you want to share about how much you wanna pay for a comp, its easier to say what components you should be looking at. Its all relative.
