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.
