Help With Dell Dimension 1100

I have a Dell Dimension 1100 and just recently got windows 7 for it, upon finding out that my graphics card is not good enough to run Windows Areo, or change my screen resolution. I was wondering if a Diamond Multimedia Stealth ATI Radeon 9250 256 MB DDR PCI Graphics Card would support windows 7 and Aero, and Support it well. please help, need to know ASAP.

No it will not even support Vista properly.

Aero hardware requirements

Your computer's hardware and video card must meet hardware requirements to able to display Aero graphics. Check that your computer meets the minimum hardware requirements for running Aero:
1-gigahertz (GHz) 32-bit (x86) or 64-bit (x64) processor

1 gigabyte (GB) of random access memory (RAM)

128-megabyte (MB) graphics card
Aero also requires a DirectX 9 class graphics processor that supports a Windows Display Driver Model Driver, Pixel Shader 2.0 in hardware, and 32 bits per pixel.

For best results, you might also want to follow these graphics processor recommendations:
64 MB of graphics memory to support a single monitor with a resolution that is less than 1,310,720 pixels (for example, a 17–inch flat panel LCD monitor that has a 1280 × 1024 resolution)

128 MB of graphics memory to support a single monitor with a resolution from 1,310,720 to 2,304,000 pixels (for example, a 21.1–inch flat panel LCD monitor that has up to a 1600 × 1200 resolution)

256 MB of graphics memory to support a single monitor with a resolution greater than 2,304,000 pixels (for example, a 30–inch wide-screen flat panel LCD monitor that has up to a 2560 × 1600 resolution)
