Agreed, you might have picked a more demanding game than crysis but I'm not sure what that would be.
The 7025 is an older integrated chip and is used for budget motherboards.
I recommend looking at adding a graphics card, at the low end an HD 4650 or 9500GT. Those would be in the $55-70 range, but they wouldn't play at high settings.
In your case, I would think about spending around $100 and look at cards like the HD4850, or the GTS 250.
