How is my new Cpu????Powerful/Powerless?

It's an entry level gaming machine, you're running at very low (by gaming standards) resolutions, in my book, low resolution is 1440x900 and under, medium is above 1440x900 to 1900x1200 and high resolution is 2560 x 1600 and up. 1024x768 is quite low. But the good news is that by running at such low resolutions, The video card won't have too much trouble maintain high frame rates. However maxing out Crysis 2 with the hardware you listed is asking a bit much, I think you'll be able to play at medium settings. However playing Crysis 2 at such low resolutions really doesn't do the game justice.
